The University

There are many electron microscope centers around the world and it is well recognized that there is no single “right” way to develop successful research and teaching electron microscope organizations.The model for this discussion is that of the Center for High Resolution Electron Microscopy (CHREM) at Arizona State University. Several factors, including but not limited to those discussed below, have contributed to the continuing growth and development of this Center.The Center serves students and faculty from eight separate academic units. It is also accessible to a significant number of microscope users from outside the university. These include researchers from industry as well as other academic institutions. The number of active instrument users typically averages eighty per year. There are ten instruments available to those who successfully complete the requirements for microscope use. It is not necessary to discuss the physical plant which houses the Center's instruments. Although very important, this topic has been adequately discussed elsewhere by experienced researchers.

The National Facility for High Resolution Electron Microscopy, within the Center for Solid State Science at Arizona State University, was established in 1979 by the National Science Foundation. The Facility was established for the purposes of advancing knowledge in the field of high resolution electron microscopy, and promoting the application of new research methods to problems of current scientific and technological importance. The current Director of the Facility is Dr. John M. Cowley.The major equipment at the Facility is as follows.JEM 4000EX 400keV ultra-high resolution electron microscope (installed 1984). Structure resolution limit of 1.7 Å, and information limit of 1.6 Å. The 4000EX can be placed under computer control (using a system developed at ASU) for the purposes of alignment; that is, the computer automatically corrects the focus, stigmation and beam tilt. At 1.7 Å resolution, direct structure images of virtually all crystalline materials can be obtained, and individual atomic columns may be resolved in many samples. The 4000EX has been applied to characterization of defects, interfaces and surfaces of ceramics, metals and semiconductors.

Recent Developments

This issue is dedicated to Regents' Professor John Maxwell Cowley, FRS, in recognition of his lifelong contributions to electron microscopy, diffraction, and crystallography. This collection of 22 peer-reviewed articles is based on presentations made at the international workshop entitled “Recent Developments and Applications of Atomic Resolution Electron Microscopy and Spectroscopy—A Silver Jubilee.” The workshop was held in the historic Old Main building on the campus of Arizona State University in early January 2003 and was attended by about 150 people. It celebrated the 25th anniversary of the Center for High Resolution Electron Microscopy, which was founded by John Cowley, and also served as an occasion to honor him on his 80th birthday. Keynote speakers included Sumio Iijima, discoverer of the carbon nanotube; Mikail Roco, senior advisor on nanotechnology for the National Science Foundation; and John Cowley himself, whose lecture addressed innovative ideas for achieving sub-Ångstrom resolution without requiring aberration correction.

High resolution electron microscopy (HREM) is a very useful technique for studying intermetallic alloy formation resulting from the interdiffusion of metals in thin films. In this work, reactions between Pt and Sn thin films are studied to elucidate mechanisms for structural and compositional changes during the interdiffusion process.Thin film specimens are prepared by the two-film method introduced by Shiojiri et al. Approximately 50 nm of Pt are vacuum-deposited onto holey carbon films mounted on 3mm diameter TEM grids. Sn films with an average thickness of 20 nm are created by evaporating Sn at rates of 1.5-3.0 nm/sec onto air-cleaved KBr substrates. The Sn films are then wet-stripped and collected on the Pt-coated holey carbon grids. A thin carbonaceous contamination layer exists between the metal films to prevent the onset of interdiffusion until the specimens are heated in situ in the TEM.TEM observations are carried out on the JEOL 2010 200kV TEM at Texas A&M University and the JEOL 4000EX 400kV TEM at Arizona State University.

This issue of Microscopy and Microanalysis contains invited and contributed papers from the 1998 Arizona State University (ASU) Workshop on In Situ Electron Microscopy, held January 7-10 at the Embassy Suites in Scottsdale, Arizona. This was the eighteenth in a series of Workshops organized annually by the Facility for High Resolution Electron Microscopy in the Center for Solid State Science at ASU. The Workshops are part of an educational program, and are intended to foster interaction and collaboration between researchers in electron microscopy. The workshop was attended by over 80 participants from universities, industries, and government laboratories around the world. Many of the contributions to the workshop are included in this issue.

Low Energy Electrons

A new field emission scanning transmission electron microscope has been constructed for the NSF HREM facility at Arizona State University. The microscope is to be used for studies of surfaces, and incorporates several surface-related features, including provision for analysis of secondary and Auger electrons; these electrons are collected through the objective lens from either side of the sample, using the parallelizing action of the magnetic field. This collimates all the low energy electrons, which spiral in the high magnetic field. Given an initial field Bi∼1T, and a final (parallelizing) field Bf∼0.01T, all electrons emerge into a cone of semi-angle θf≤6°. The main practical problem in the way of using this well collimated beam of low energy (0-2keV) electrons is that it is travelling along the path of the (100keV) probing electron beam. To collect and analyze them, they must be deflected off the beam path with minimal effect on the probe position.

The Relationship

This paper illustrates a case study of teaching and research applied to the abandoned mining landscapes of the Sulcis area, located in the south-east side of Sardinia, one of the poorest in Europe. Although the region’s critical condition in the present, the area is nevertheless extremely rich in fascination and history. It offers unique natural landscapes, mostly pristine, a variety of archeological sites and, as mentioned, the ruins of the mining installations. All of this makes fore-seeable a concrete possibility of regeneration for the area, based on tourism, one of the island primary resources. The local institutions of Sulcis started a partnership with the University of Cagliari aiming to pursuit not just a practical and economical outcome in the immediate present, more a cultural and deeper rescue with a wider perspective. In the following pages, we present our academic activities in this mark and how we managed to guarantee fruitful superpositions of pedagogy, design, and research in our work within this kind of cooperation.Our focus is, therefore, the relationship between researching and teaching activities and the actions in support of the territory, pursued in a joint venture with the political institution. During these experiences, we defined a strategy to intercross these different layers, bringing the real and concrete dimension into our classroom, sharing our work with the students, and, at the same time, transferring the fruits of the teaching experiences to the territory. The correspondence between these two levels is not free of ambiguity and contradictions, however, we are convinced that it might show very important and fruitful outcomes.
