Facts and Achievements 2015 Preface
Facts and Achievements 2015 Preface Masakazu Aono MANA Director-General NIMS The International Center for Materials Nanoarchitectonics (MANA) was founded in 2007 as one of the first five centers under the World Premier International Research Center Initiative (WPI Program) of Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT). In all the way of this period, MANA has conducted its research on the basis of our own “nanoarchitectonics” concept. All the members of MANA including permanent scientists, postdoctoral researchers, technical and administrative staff and students are happy to see that MANA has become a really world-top-level research center in the field of material science and technology. In fact, until December 2015, MANA has published 3,316 papers in 422 different journals and 118 of them are now among the top 1% most cited papers in the world. Further, MANA has achieved an extremely high score of 2.42 for Elsevier’s Field Weighted Citation Impact (FWCI), a new index created to “fairly compare the quality of papers published by research institutions that work in different fields.” MANA’s papers are printed in journals with an extremely high average Impact Factor (IF) of 6.25 (2015). MANA’s scores for these indicators are superior to those of many world-class research institutions. The MANA Progress Report consists of two booklets named “Facts and Achievements 2015” and “Research Digest 2015.” This booklet “Facts and Achievements 2015” serves as a summary to highlight the progress of the MANA project. The other booklet “Research Digest 2015” presents MANA research activities. -

The question providing the theme for the present issue of Philosophia Scientiæ is, of course, adapted from Richard Feynman’s well-known speech at the 1959 meeting of the American Physical Society. On this occasion he attracted physicists’ attention to the vast potential of working at the scale of the nanometre if not the ångström, using the catchy title: “Plenty of Room at the Bottom” [Feynman 1959]. This hookline from a famous Nobel laureate physicist served as a motto for the emerging field of nanoscience and nanotechnology (which we will here abbreviate to nanoresearch) in the early 2000s. -

These nanocars, or molecule-cars, can have real wheels and a chassis, and move using energy from electric pulses. This energy is provided by a specific instrument, known as a scanning tunneling microscope. Using a small electric current, the microscope's tip can visualize small objects, some up to 30,000 times smaller than a strand of hair. These electric pulses also enable the nanocars to move. Microscopes of this type usually have only one tip. However, the CNRS's Centre d'élaboration de matériaux et d'études structurales (CEMES) in Toulouse has a unique instrument with four independently controlled tips—ideal for organizing a race and simultaneously driving four different molecule-cars! Four teams, each with its own driving seat, will test four different molecular machines using the same microscope—and will do so at the same time and on the same surface. -

Department of Chemistry, University of Basel, Spitalstrasse 51 4056 Basel, Switzerland § E-mail: [email protected] Abstract The surface diffusion of individual molecules is of paramount importance in self- assembly processes and catalytic processes. However, the fundamental understand- ing of molecule diffusion peculiarities considering conformations and adsorption sites remain poorly known at the atomic-scale. Here, we probe the 4’-(4-tolyl)-2,2’:6’,2”- terpyridine adsorbed on the Au(111) herringbone structure combining scanning tun- neling microscopy and atomic force microscopy. Molecules are controllably translated by electrons excitations over the reconstruction, except at elbows acting as pinning 1 centres. Experimental data supported by theoretical calculations show there the for- mation of coordination bonds between the molecule and Au atoms of the surface. Using force spectroscopy, we quantify local variation of the surface potential and the lateral force required to move the molecule. We found an elevation of the diffusion barrier at elbows of the reconstruction of 100 meV compared to the rest of the surface. ∼ Keywords: atomic force microscopy, single-molecule, scanning tunneling microscopy, force spectroscopy, molecular machine. -

Mier Valdivia Submitted to the Department of Physics on May 11, 2018, in partial fulfillment of the requirements for the degree of Bachelor of Science in Physics Abstract In this work, we studied the chiral charge density wave (CDW) phase in titanium diselenide (TiSe 2) with the circular photogalvanic effect (CPGE). Mechanically exfo- liated bulk TiSe 2 flakes were obtained and implemented into nanoscale devices using standard fabrication techniques. Four samples' photocurrent response to a 120 meV laser was subsequently measured as a function of temperature and laser power. The onset of the CPGE at approximately 174 K confirms the emergence of chiral order below the regular CDW transition at 197 K. Furthermore, we were able to train the chirality of the system by cooling it while shining circularly polarized light. With this study, we have confirmed that TiSe2 is a novel kind of material that spontaneously breaks inversion, all mirror, and roto-inversion symmetries and attains gyrotropic order, paving the way for future experimental work on similar condensed matter sys- tems. -
