Book excerpt: The authors present the design and first results of a low-temperature, ultrahigh vacuum scanning probe microscope enabling atomic resolution imaging in both scanning tunneling microscopy (STM) and noncontact atomic force microscopy (NC-AFM) modes. A tuning-fork-based sensor provides flexibility in selecting probe tip materials, which can be either metallic or nonmetallic. When choosing a conducting tip and sample, simultaneous STM/NC-AFM data acquisition is possible. Noticeable characteristics that distinguish this setup from similar systems providing simultaneous STM/NC-AFM capabilities are its combination of relative compactness (on-top bath cryostat needs no pit), in situ exchange of tip and sample at low temperatures, short turnaround times, modest helium consumption, and unrestricted access from dedicated flanges. The latter permits not only the optical surveillance of the tip during approach but also the direct deposition of molecules or atoms on either tip or sample while they remain cold. Atomic corrugations as low as 1 pm could successfully be resolved. In addition, lateral drifts rates of below 15 pm/h allow long-term data acquisition series and the recording of site-specific spectroscopy maps. Results obtained on Cu(111) and graphite illustrate the microscope's performance.

Available in PDF, EPUB and Kindle. Book excerpt: Literature Review from the year 2015 in the subject Engineering - General, Indian Institute of Technology, Delhi, course: Mineral Engineering, language: English, abstract: Atomic-scale resolution is needed to study the arrangement of atoms in materials and advancing their understanding. Since the seventeenth-century optical microscopes using visible light as illumination source have led our quest to observe microscopic species but the resolution attainable reached physical limits due to the much longer wavelength of visible light. After the discovery of wave nature associated with particle bodies, a new channel of thought opened considering much shorter wavelength of particles and their special properties when interacting with the sample under observation. These particles i.e. electrons, neutrons and ions were developed in different techniques and were used as illumination sources. Herein, the development of scanning tunneling microscopy which used electrons to uncover irregularities in the arrangement of atoms in thin materials via the quantum mechanical phenomenon of electron tunneling became a sensational invention. Atomic Force Microscopy (AFM) is a development over STM which relied on measuring the forces of contact between the sample and a scanning probe which overcame the earlier technique only allowing conductors or pretreated surfaces for conducting to be observed. Since measuring contact forces between materials is a more fundamental approach that is equally but more sensitive than measuring tunneling current flowing between them, atomic force microscopy has been able to image insulators as well as semiconductors and conductors with atomic resolution by substituting tunneling current with an atomic contact force sensing arrangement, a delicate cantilever, which can image conductors and insulators alike via mechanical "touch" while running over surface atoms of the sample. AFM has seen a massive proliferation in hobbyist’s lab in form of ambient-condition scanning environment as opposed to an ultra-high vacuum of sophisticated labs and self-assembled instrumentations. The success of ATM as a cost-effective imaging tool with dramatically increased ease of conceptual understanding and use particularly with the assistance of significant computing power in the form of personal computers which offsets the computational difficulty of resolving experimental information which makes up for physical simplicity of instrument design has seen its proliferation to numerous labs in universities and technology companies worldwide.

This book was released on 2013-06-29 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the compilation of papers presented at the second Atomic Force Microscopy/Scanning Tunneling Microscopy (AFM/STM) Symposium, held June 7 to 9, 1994, in Natick, Massachusetts, at Natick Research, Development and Engineering Center, now part ofU.S. Army Soldier Systems Command. As with the 1993 symposium, the 1994 symposium provided a forum where scientists with a common interest in AFM, STM, and other probe microscopies could interact with one another, exchange ideas and explore the possibilities for future collaborations and working relationships. In addition to the scheduled talks and poster sessions, there was an equipment exhibit featuring the newest state-of-the-art AFM/STM microscopes, other probe microscopes, imaging hardware and software, as well as the latest microscope-related and sample preparation accessories. These were all very favorably received by the meeting's attendees. Following opening remarks by Natick's Commander, Colonel Morris E. Price, Jr., and the Technical Director, Dr. Robert W. Lewis, the symposium began with the Keynote Address given by Dr. Michael F. Crommie from Boston University. The agenda was divided into four major sessions. The papers (and posters) presented at the symposium represented a broad spectrum of topics in atomic force microscopy, scanning tunneling microscopy, and other probe microscopies.

Army Natick Research, Development and Engineering Center Atomic Force/Scanning Tunneling Microscopy (AFM/STM) Symposium was held on lune 8-10, 1993 in Natick, Massachusetts. This book represents the compilation of the papers presented at the meeting. The purpose ofthis symposium was to provide a forum where scientists from a number of diverse fields could interact with one another and exchange ideas. The various topics inc1uded application of AFM/STM in material sciences, polymers, physics, biology and biotechnology, along with recent developments inc1uding new probe microscopies and frontiers in this exciting area. The meeting's format was designed to encourage communication between members of the general scientific community and those individuals who are at the cutting edge of AFM, STM and other probe microscopies. It immediately became clear that this conference enabled interdisciplinary interactions among researchers from academia, industry and government, and set the tone for future collaborations. Expert scientists from diverse scientific areas including physics, chemistry, biology, materials science and electronics were invited to participate in the symposium. The agenda of the meeting was divided into three major sessions. In the first session, Biological Nanostructure, topics ranged from AFM ofDNA to STM imagmg ofthe biomoleeule tubulin and bacterialluciferase to the AFM of starch polymer double helices to AFM imaging of food surfaces.
