Brown Acting Director Subject: Charge to the National Research Council Board on Assessment of NIST Programs for the FY 2002 Evaluation I am extremely grateful to the members of the Board on Assessment and its panels for the time, effort, and expertise that all of you devote to evaluating the technical quality of the National Institute of Standards and Technology’s (NIST’s) laboratory programs. Your findings are a central component of our performance evaluation system and help NIST remain a top-quality science and technology agency serving the nation’s measurement needs. NIST highly values your hard work and insights in assessing our laboratory programs, and we look forward to working closely and productively with you in FY 2002. NIST’s mission is to develop and promote measurement, standards, and technology to enhance productivity, facilitate trade, and improve the quality of life. The NIST Laboratories conduct research to anticipate future metrology and standards needs, to enable new scientific and technological advances, and to continuously improve and refine existing measurement methods and services. For FY 2002, 1 ask that the Board on Assessment continue your longstanding focus on assessing the technical merit and relevance of NIST’s laboratory programs. I also ask the Board to continue your focus on assessing the relevance of NIST work to the needs of our customers, a focus first emphasized last year. Potential demand for NIST measurement and standards will always exceed our limited resources. We ask the Board to continue to help us maximize the impact of our laboratory programs by focusing on the most significant needs of our customers. In summary, I ask the Board on Assessment to focus its FY 2002 assessment of the NIST Laboratories on four factors: • the technical merit of the laboratory programs relative to the state-of-the-art worldwide; • the effectiveness with which the laboratory programs are carried out and the results disseminated to their customers; • the relevance of the laboratory programs to the needs of their customers; and NIST • the ability of the Laboratories’ facilities, equipment, and human resources to enable the Laboratories to fulfill their mission and meet their customers’ needs. With its mix of experts from industry, academia, and government agencies, the Board is well positioned to help NIST evaluate its laboratory programs on each of these factors. As in past years, your findings will be valued not only by NIST but also by the Department of Commerce, the Administration, and Congress as they strive to ensure an optimal return on the public’s investment in NIST. The Board’s reports, statements, and briefings—based on independent and comprehensive expert peer review—are a cornerstone of NIST’s performance evaluation system and are featured prominently in our reports to the Administration and Congress under the terms of the Government Performance and Results Act (GPRA). The Board’s annual published assessment is a thorough and comprehensive document of great value to NIST and our stakeholders. I would also like to discuss the opportunity for the Board to provide a brief executive summary in addition to the complete assessment to help more broadly disseminate the Board’s key findings. NIST expects that future scientific and technology advances will continue to be more interdisciplinary, including such fields as biosciences and health care, information technology, and nanotechnology. We thank the Board for their insight in experimenting with crosscutting panels to assess some of NIST’s interdisciplinary work, including the FY 2001 review of microelectronics programs and the upcoming FY 2002 review of measurement services. We look forward to working closely with the NRC BoA to evaluate the value and effectiveness of these reviews within the context of the overall review process. The Board can further help NIST’s performance evaluation process by tracking over time NIST’s responses to the Board’s findings and recommendations. Thus I ask the Board to include in your FY 2002 evaluation an assessment of NIST’s responses to your FY 2001 report. I look forward to discussing with the Board the possibility of systematically tracking NIST’s responses to your findings and recommendations from year to year and over several years in future evaluations. Thank you again for contributing your time and expertise to assess the quality and relevance of NIST’s laboratory programs. Your expert, objective appraisal is crucial to helping NIST continuously improve its programs and effectiveness. cc: Executive Board Program Office Dorothy Zolandz — PHYSICS LABORATORY ANNUAL REPORT MESSAGE TO THE PANEL FOR PHYSICS Katharine B.

An inherent issue of these techniques is the deformation of the polymer carrier film during the transfer, which can lead to highly non-uniform strain 1 induced in the transferred two-dimensional material. Here, using a combination of op- tical spectroscopy, atomic force and Kelvin probe force microscopy, we show that the presence of nanometer scale wrinkles formed due to transfer-induced stress relaxation can lead to strong changes in the optical properties of MoSe2/WSe2 heterostructures and the emergence of the linearly polarized interlayer exciton

  • Infrastructure Needs for R&D and Education
    153 Chapter 11 INFRASTRUCTURE NEEDS FOR R&D AND EDUCATION Contact persons: J.L. Merz, Notre Dame University; A. Ellis, University of Wisconsin 11.1 VISION A substantial infusion of resources is needed for enhancement of fabrication, processing, and characterization equipment that must be made available to large numbers of users in the nanostructure community. It is also necessary to continue the process, already underway, of modifying the culture of universities to enable more interdisciplinary research to prosper, as well as to enable more industrial cooperation. 11.2 CURRENT INFRASTRUCTURE Infrastructure for Research and Development A major impediment to the growth of a viable nanostructure science and technology effort in the United States is an outcome of its strength: this is inherently a multidisciplinary activity. Many feel that the emphasis in this activity will shift in coming decades from the physical to the biological and life sciences. The fact that this is already happening is significant, but it is impeded by the lack of a suitable infrastructure supporting interactions among what have traditionally been very disparate disciplines. This chapter includes examples and describes in greater detail the unusual aspects of those programs that could be emulated by others to the benefit of the field overall. The infrastructure for nanoscience and technology is only in formation, and is undersized compared to the needs and overall promise of the nanotechnology field. Education Although change is occurring in universities in a relatively

Even for weakly informative priors, GP methods allow unambiguous determination of the characteristic length scales of the imaging process both in spatial and frequency domains. We further show that BE data set tends to be oversampled, with ~30% of original data set sufficient for high-quality reconstruction, potentially enabling the faster BE imaging.

  • 07-AFM Probing the Nanoworld
    MT.7 Handbook of instrumental techniques from CCiTUB Atomic Force Microscopy: probing the Nanoworld Gerard Oncins and Jordi Díaz-Marcos Unitat de Tècniques Nanomètriques, CCiTUB, Universitat de Barcelona. Lluís Solé i Sabarís, 1-3. 08028 Barcelona. Spain. email: [email protected] Abstract . Atomic Force Microscope and related techniques have played a key role in the development of the nanotechnology revolution that is taking place in science. This paper reviews the basic principles behind the technique and its different operation modes and applications, pointing out research works performed in the Nanometric Techniques Unit of the CCiTUB in order to exemplify the vast array of capabilities of these instruments. Atomic Force Microscopy 1. Introduction Since Richard Feynman sentenced that “there is plenty of room at the bottom” in the 50’s, nanoscience and nanotechnology have become two of the cornerstones of modern science. Nanotechnology, thanks to its interdisciplinary nature, is spreading fast in a variety of disciplines comprising, among others, engineering, physics, chemistry and life sciences. Although we usually assume that nano keeps on being a matter of theorists, there are plenty of daily life products that MT.7 benefit from this new and revolutionary approach. Microelectronics is the most obvious field, as microprocessors and microfabricated parts are becoming smaller and more powerful. Nevertheless, life sciences, medicine and cosmetics are increasingly introducing nanoparticles in common products as solar filters and anti-ageing treatments [1]. These sorts of products have become controversial because they have not been intensively tested in human beings and long-term effects remain unknown [1]. The nanometric diameter of nanoparticles enables them to cross the skin- barrier and entering the blood stream, thus being possibly involved in a variety of cancers.

    Exploring the nanoworld with atomic force microscopy Franz J. Giessibl and Calvin F. Quate Over its 20-year history, the atomic force microscope has gradually evolved into an instrument whose spatial resolution is now fine enough to image subatomic features on the scale of picometers. Franz Giessibl is a professor of physics at the University of Regensburg and the University of Augsburg in Germany. Calvin Quate is a professor of electrical engineering and applied physics at Stanford University in California. In 1985 Gerd Binnig and Christoph Gerber took a original 1986 paper, which ranks it among the 10 most-cited temporary leave from IBM’s Zürich Research Laboratory in articles in Physical Review Letters.

In scanning probe microscopes, the nanoprobes consist on silicon tips coated with thin metallic films to provide additional properties, such as conductivity. However, if the experiments involve high currents or lateral frictions, the initial properties of the tips can wear out very fast. One possible solution is the use of hard coatings, such as diamond, or making the entire tip out of a precious material (platinum or diamond). However, this strategy is more expensive and the diamond coatings can damage the samples. In this context, the use of graphene as a protective coating for nanoprobes has attracted considerable interest. Here we review the main literature in this field, and discuss the fabrication, performance and scalability of nanoprobes. Keywords: graphene; nanoprobes; coatings; atomic force microscopy; wear 1. Introduction Sharp probe tips with an apex radius <100 nm are widely used in many different fields of science including electronics [1], physics [2], chemistry [3], biology [4] and medicine [5], as they allow local characterization and manipulation of materials with a nanometric spatial resolution.
