Book Restoration of a Low Temperature Scanning Tunneling Microscope

Download or read book Restoration of a Low Temperature Scanning Tunneling Microscope written by Baird Bankovic and published by . This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scanning tunneling microscopy is a technique that enables the study of the surfaces of materials with sub-nanometer resolution. A scanning tunneling microscope (STM) gives local electronic information about the surface and is an invaluable analysis technique in modern condensed matter physics. The goal of my project was to restore an existing low temperature STM which had fallen into disrepair. This thesis outlines the restoration process, along with a description of the supporting techniques that were necessary. In parallel with the restoration process, I also developed an automated tungsten tip fabricator for making atomically sharp tips for the STM. This is an original design that I have shared on an open source website. Additionally, I explored the use of a low temperature transimpedance preamplifier that would improve the performance of our STM and tested a number of operational amplifiers that could be used to this end.

Book Scanning Tunneling Microscopy and Its Application

Download or read book Scanning Tunneling Microscopy and Its Application written by Chunli Bai and published by Springer Science & Business Media. This book was released on 2000-08-10 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified view of the rapidly growing field of scanning tunneling microscopy and its many derivatives. After examining novel scanning-probe techniques and the instrumentation and methods, the book provides detailed accounts of STM applications. It examines limitations of the present-day investigations and provides insight into further trends. "I strongly recommend that Professor Bai's book be a part of any library that serves surface scientists, biochemists, biophysicists, material scientists, and students of any science or engineering field...There is no doubt that this is one of the better (most thoughtful) texts."

Book Combined Low temperature Scanning Tunneling

Download or read book Combined Low temperature Scanning Tunneling written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. 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.

Book Ultrafast Scanning Tunneling Microscopy Using a Photoexcited Low temperature grown Gallium Arsenide Tips

Download or read book Ultrafast Scanning Tunneling Microscopy Using a Photoexcited Low temperature grown Gallium Arsenide Tips written by and published by . This book was released on 1998 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invention of the scanning tunneling microscope (STM) revolutionized the field of surface science, enabling the first images of surface structure on an atomic length scale. In the quest for both atomic spatial and temporal resolution several groups have integrated an ultrafast optoelectronic switch which gates the current from the tip, achieving picosecond time resolution. In this paper, the authors describe a novel STM tip consisting of a cleaved GaAs substrate with a 1-[mu]m thick epilayer of low-temperature-grown GaAs (LT-GaAs) deposited on the face. Since the LT-GaAs has a carrier lifetime of 1 ps, photoexcitation of the tip with an ultrafast, above-bandgap pulse both provides carriers for the tunneling current and photoconductively gates (with ps resolution) the current from the tip. They use this tip to detect picosecond transients on a coplanar stripline and demonstrate a temporal resolution of 1.2 ps in tunneling mode.
