Project Details

Description

The purpose of this proposal is to seek support for an annual school in the field of high resolution transmission electron microscopy (TEM). The school is scheduled to be held from January 7 11th, 2013 at Arizona State University. Atomic-resolution transmission electron microscopy (TEM) continues to grow in importance for the analysis of advanced materials. The combination of atomic-resolution imaging with subnanometer spectroscopy allows the structure, composition and local bonding of solids to be mapped out with unsurpassed detail. The continuing evolution of instrumentation challenges the community to constantly evaluate and improve training methodologies to ensure that users are able to operate the newest microscopes at their performance limits. With most advanced techniques in the TEM, mastery in terms of data acquisition and interpretation is only possible when guided by full knowledge of fundamental principles which are best learned through a combination of lectures, demonstrations and handson practice. The ultimate goal of any advanced microscopy training should thus be to provide users with the skills needed to acquire high quality data sets, to process the information and to interpret the final results. Modern instruments equipped with software control have greatly enhanced the ease of operation. However, like any other activity, complete mastery can only be accomplished through intensive study and practice. As a service to the broader microscopy community, ASU organizes an annual Winter School on High Resolution Electron Microscopy. These began in 1982 when the first one was organized by Ondrej Krivanek. Later Schools were organized by David Smith, Peter Rez, and by Ray Carpenter and Peter Crozier. The Schools and workshops are well attended, with scholarships supported by industry provided for many grad students. The School lasts 5 days and usually consists of three lectures in the mornings and two laboratory sessions in the afternoons. The curriculum has evolved to cover many aspects of electron diffraction, imaging, spectroscopy and simulation. The enrollment is typically capped at about 45 people to ensure that small lab groups can be formed, so participants can get hands-on experience during the sessions. Lectures are given by many of the ASU faculty specialists and by outstanding invited microscopists from other labs worldwide. Most of the same group as well as ASU postdocs and support staff conduct the labs, using nearly all the microscopes at ASU. The broad spectrum of expertise present provides a very powerful learning environment for the students, including many one-on-one discussions that follow the lectures and labs. The purpose of the school is to introduce the theory and practice of high resolution electron microscopy to scientists currently using transmission electron microscopes for nanoscience studies. Lecture topics will include: Fundamentals of HREM; Imaging Theory; Transfer Functions in HREM; Electron Diffraction; Small Probe Formation; Fundamentals of STEM; Practical HREM/STEM Operation; In Situ TEM; Image Processing Techniques; Convergent Beam Microdiffraction; Electron Energy-Loss Spectroscopy; Energy Dispersive X-ray Spectroscopy; Focused Ion Beam (FIB) methods Arizona State University has outstanding TEM facilities housed in the LeRoy Eyring Center for Solid State Science. We have access to 7 TEMs which are incorporated into 7 different lab classes which emphasize all aspects of electron imaging, diffraction and spectroscopy. The TEM facilities also include an aberration corrected scanning transmission electron microscope which will be utilized in the Winter School. The course features extended practical sessions using the JEOL ARM, FEI Tecnai, JEM 2010F, JEM 4000EX, Topcon 002B, and FEI CM200, where specific operating techniques will be taught. The emphasis is"hands on" experience of microscope operation. There will also be sessions on image processing and simulations using advanced digital image processing programs. Lectures and laboratory demonstrations will be given by ASU faculty and CHREM staff, as well as invited expert speakers. Demonstrations of environmental electron microscopy, focused ion beam methods and techniques of specimen preparation will also be scheduled. The course is taught by a group of internationally reknown experts in the field of TEM and typically includes Prof. R.F. Egerton University of Alberta Prof. M. Watanabe Lehigh University Prof. J.M. Zuo University of Illinois at Champaign-Urbana Dr. R. Sharma CNST, NIST Dr. L. Giannucci - L.A. Giannuzzi& Associates LLC Prof. P.A. Crozier Arizona State University Prof. D.J. Smith Arizona State University Prof. M.R. McCartney Arizona State University Prof. J. Liu Arizona State University Dr Sharma is a Project Leader at CNST and has agreed to serve as lecturer and lab instructor for the school. She will also provide input and guidance from NIST in developing and updating the curriculum especially with regard to high resolution and in situ transmission electron microscopy
