The meeting continues a series of biennial conferences, which was started in Durham, UK, in 1983. The latest conferences were held in Niagara Falls (2003), Warsaw (2005), and Jeju Island (2007). The Conference is organized by the Ioffe Physical Technical Institute of RAS, one of the leading research centers in the world in the field of semiconductor physics and technology. It is famous for numerous discoveries in the field, including pioneering studies of excitonic properties of II-VI compounds. The purpose of the current II-VI compound Conference is to bring together scientists from all over the world, which are active in the fields of basic and applied research of II-VI structures. The Conference Program reflects a revival of interest in the recent years to this group of materials due to the emergence of many fascinating ideas and prospects as well as the development of new technologies. In particular, the wide band gap semiconductors like ZnO, (Zn,Cd)Te, (Zn,Cd)Se provide unique opportunities to exploit the ideas of photonic-band engineering in specially designed quantum nanostructures. This intense activity has yet resulted in the observation of numerous original effects and emergence of new device concepts, including Bose condensation of exciton polaritons ("polariton laser"), triggered single-photon sources for quantum cryptography, optical switches and memories. Important areas that take advantage of the specific properties of II-VI compounds are quantum information processing and spintronics, since II-VI non-magnetic and diluted magnetic semiconductors and quantum dots are ideal objects for experimental modeling of the devices employing the spin degree of freedom. Among other prospective practical applications of the II-VI compounds which will be presented are yellow-to-blue lasers with different pumping types, infrared detectors, terahertz emitters, inter-subband devices like quantum cascade lasers, and nanoscale sensors. A special feature of the 14th Conference is organizing the Session of Review Lectures delivered by most prominent scientists in the field. The attendance of the present conference is relatively high and world wide: approximately 300 scientists from 26 countries. Beside the Review lecturers, we have 21 invited talks, 60 oral and ~200 poster presentations. The Conference proceedings will be published in a special issue of the Physica Status Solidi (c) not later than early spring 2010. We would like to thank on behalf of the Organizing Committee all the sponsors listed subsequently for their substantial support. Without their help it would have been impossible to hold the registration fee low for young physicists, which has allowed many of them to participate in this meeting. We wish all participants an enjoyable and successful meeting. S.A. Permogorov S.V. Ivanov A.A.

Dr. h.c. mult. Gottfried LANDWEHR was born on 22.08.1929 in Osnabrück, Germany. After studying physics at Technical University Karlsruhe, he joined the German National Bureau of Standards Physikalisch Technische Bundesanstalt (PTB), Braunschweig, starting to work on semiconductors and investigating defect-induced electrons in germanium. After his Dissertation (Ph.D.), Gottfried LANDWEHR went to the University of Illinois, Urbana, where he collaborated e.g. with Prof. John BARDEEN (1959-1961), in 1961 he became Assistant Professor there. Back in Germany he became the Head of the President´s Laboratory at the PTB and a member of faculty of Technical University Braunschweig. In 1968, he accepted a position at Würzburg Unversity, Germany, as the chairholder for Experimentelle Physik III and initiated his fundamental research on semiconductors in high magnetic fields peaking up later in the investigations of Q2D-semiconductor systems. In those days he also initiated the famous conference series “Semiconductors in High Magnetic Fields”. Between 1978 and 1983, Gottfried LANDWEHR was director of the Hochfeldmagnetlabor des Max Planck-Institutes für Festkörperforschung in Grenoble, France. Under his directorship there Klaus von KLITZING made his famous measurements on the Quantum Hall Effect, later awarded by the Nobel Prize. Back at Würzburg University, Gottfried LANDWEHR started working on II-VI semiconductor layered structures grown by molecular beam epitaxy, with substantial contributions especially in the field of semimagnetic semiconductors, but also narrow gap HgCdTe as well as ZnSe based laser diodes. His overall achievements and world- wide scientific interactions made Gottfried LANDWEHR an internationally well renowned scientist with tremendous reputation. He is a member of the Bavarian Academy of Sciences. Prof. LANDWEHR made a considerable contribution to the development of collaboration between German and Russian scientists, in particular from the Ioffe Institute. This his activity was highly evaluated by electing him as External Member of the Russian Academy of Sciences and Honorary Member of the Ioffe Institute, St. Petersburg. During the II-VI-2009 Conference a Complimentary Session will be held to mark the 80th birthday of Prof. Gottfried LANDWEHR, the Honorary Chair of the Conference. 4 14th International Conference on II-VI Compounds, August 23-28, 2009, St. Petersburg, Russia 14th International Conference on II-VI Compounds, August 23-28, 2009, St. Petersburg, Russia Honorary Chair G.

Most immediately we have to thank Sandra Bürden at the Resources Centre, who assembles the pages on her computer and who is to thank for much of the fine detail of the magazine's final appearance: I am hugely indebted to her for her energy, initiative and attention to detail. Earlier in the chain stand the section editors, whose job is to round up copy and pictures for their sections and devise the running order and general page layouts for that section. They also have to go in for a good deal of rewriting: prolixity must be trimmed, irrelevance eliminated, errors put right and facetiousness filtered out. To be a good editor requires not only a good ear for language and a high level of compétence in written English: it also calls for patience and good humour in the actual pursuit of material. Mirabile dictu, it sometimes happens that contributors to the magazine are strong on promises but weak on performance. This year's editors have been terrifie.

    LUNAR TOPOGRAPHIC ORTHOPHOTOMAP (LTO) AND LUNAR ORTHOPHOTMAP (LO) SERIES (Published by DMATC) Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Scale: 1:250,000 Projection: Transverse Mercator Sheet Size: 25.5”x 26.5” The Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Series are the first comprehensive and continuous mapping to be accomplished from Apollo Mission 15-17 mapping photographs. This series is also the first major effort to apply recent advances in orthophotography to lunar mapping. Presently developed maps of this series were designed to support initial lunar scientific investigations primarily employing results of Apollo Mission 15-17 data. Individual maps of this series cover 4 degrees of lunar latitude and 5 degrees of lunar longitude consisting of 1/16 of the area of a 1:1,000,000 scale Lunar Astronautical Chart (LAC) (Section 4.2.1). Their apha-numeric identification (example – LTO38B1) consists of the designator LTO for topographic orthophoto editions or LO for orthophoto editions followed by the LAC number in which they fall, followed by an A, B, C or D designator defining the pertinent LAC quadrant and a 1, 2, 3, or 4 designator defining the specific sub-quadrant actually covered. The following designation (250) identifies the sheets as being at 1:250,000 scale. The LTO editions display 100-meter contours, 50-meter supplemental contours and spot elevations in a red overprint to the base, which is lithographed in black and white. LO editions are identical except that all relief information is omitted and selenographic graticule is restricted to border ticks, presenting an umencumbered view of lunar features imaged by the photographic base.

  • Viscosity from Newton to Modern Non-Equilibrium Statistical Mechanics
    Viscosity from Newton to Modern Non-equilibrium Statistical Mechanics S´ebastien Viscardy Belgian Institute for Space Aeronomy, 3, Avenue Circulaire, B-1180 Brussels, Belgium Abstract In the second half of the 19th century, the kinetic theory of gases has probably raised one of the most impassioned de- bates in the history of science. The so-called reversibility paradox around which intense polemics occurred reveals the apparent incompatibility between the microscopic and macroscopic levels. While classical mechanics describes the motionof bodies such as atoms and moleculesby means of time reversible equations, thermodynamics emphasizes the irreversible character of macroscopic phenomena such as viscosity. Aiming at reconciling both levels of description, Boltzmann proposed a probabilistic explanation. Nevertheless, such an interpretation has not totally convinced gen- erations of physicists, so that this question has constantly animated the scientific community since his seminal work. In this context, an important breakthrough in dynamical systems theory has shown that the hypothesis of microscopic chaos played a key role and provided a dynamical interpretation of the emergence of irreversibility. Using viscosity as a leading concept, we sketch the historical development of the concepts related to this fundamental issue up to recent advances. Following the analysis of the Liouville equation introducing the concept of Pollicott-Ruelle resonances, two successful approaches — the escape-rate formalism and the hydrodynamic-mode method — establish remarkable relationships between transport processes and chaotic properties of the underlying Hamiltonian dynamics. Keywords: statistical mechanics, viscosity, reversibility paradox, chaos, dynamical systems theory Contents 1 Introduction 2 2 Irreversibility 3 2.1 Mechanics. Energyconservationand reversibility . ........................ 3 2.2 Thermodynamics.

The principal point of this program was a detailed scientific analysis of the orbital and surface experiments data derived from Apollo missions 15, 16, and 17. One of the requirements of this program was the production of detailed photo base maps at a useable scale. NASA in conjunction with the Defense Mapping Agency (DMA) commenced a mapping program in early 1973 that would lead to the production of the necessary maps based on the need for certain areas. This paper is designed to present in outline form the neces- sary background informatiox or users to become familiar with the program. MAP FORMAT * The scale chosen for the project was 1:250,000 . The re- search being done required a scale that Principal Investigators (PI'S) using orbital photography could use, but would also serve PI'S doing surface photographic investigations. Each map sheet covers an area four degrees north/south by five degrees east/west.

  • Conditions for the Existence of Backward Surface Magnetostatic Waves in a Ferrite–Insulator–Metal Structure V
    TECHNICAL PHYSICS LETTERS VOLUME 24, NUMBER 7 JULY 1998 Conditions for the existence of backward surface magnetostatic waves in a ferrite–insulator–metal structure V. I. Zubkov and V. I.

A theoretical analysis is made of the dispersion of surface magnetostatic waves ~SMSWs! at different frequencies propagating in ferrite–insulator–metal ~FIM! structures magnetized by a uniform magnetic field. It is established that depending on the ratio between the thicknesses of the ferrite and insulating layers in FIM structures, backward SMSWs exist in different frequency ranges and have different wave numbers and directions of propagation. The conditions for which backward SMSWs may be observed directly in FIM structures are determined. © 1998 American Institute of Physics. @S1063-7850~98!00107-4# Studies of the dispersion of forward and backward sur- with varying VH , whereas the angle w is considered to be a face magnetostatic waves ~SMSWs! in ferrite–insulator– free parameter which is defined by the antenna exciting the metal ~FIM! structures are of great interest because of their SMSW (w5w0) ~Refs. 1–6!.

This document constitutes LSI Contribution No. 206 March 1975 USER GUIDE TO 1 : 250 , 000 SCALE LUNAR MAPS GENERAL In 1 972 the NASA Lunar Programs Office initiated the Apoll o Photographic Data Analysis Program. The principal point of this program was a detail ed scientific analysis of the orbital and surface experiments data derived from Apollo missions 15, 16, and 17 . One of the requirements of this program was the production of detailed photo base maps at a useabl e scale . NASA in conjunction with the Defense Mapping Agency (DMA) commenced a mapping program in early 1973 that would lead to the production of the necessary maps based on the need for certain areas . This paper is desi gned to present in outline form the neces- sary background information for users to become familiar with the program. MAP FORMAT The scale chosen for the project was 1:250,000* . The re- search being done required a scale that Principal Investigators (PI's) using orbital photography could use, but would also serve PI's doing surface photographic investigations. Each map sheet covers an area four degrees north/south by five degrees east/west. The base is compiled from vertical Metric photography from Apollo missions 15, 16, and 17.
