Full Symposium Descriptions

Instrumentation & Techniques Symposia
A1 Oliver Wells Memorial Symposium on the Scanning Electron Microscope

Lynne M. Gignac, David C. Joy, Brendan J. Griffin

Dr. Oliver C. Wells was one of Sir Charles Oatley’s first students to work on the scanning electron microscope (SEM) at Cambridge University and is widely considered one of the pioneers of the commercial SEM. For most of his 60 year career, Dr. Wells studied various aspects of the SEM but had particular interests in “low loss”, energy filtered and very high energy (>100 keV) SEM imaging, SEM electron detector design and practical applications, and studying ways to reduce charging in SEM. Dr. Wells passed away in 2013 and this symposium is intended to honor his memory and legacy by soliciting papers on research, development, history and uses of the SEM with a particular emphasis on his research interests.

A2 Advances in Imaging and Spectroscopy in STEM

Nigel D. Browning, Peter D. Nellist, Maria Varela del Arco

In the 25 years since the first demonstration of atomic resolution Z-contrast imaging, STEM has risen from a technique performed only at a select few institutions to a ubiquitous method for atomic scale imaging and analysis. The aim of this symposium is to provide a forum to discuss the key developments that brought us to this stage and how the lessons learned from along the way can enhance the future development and integration of STEM methods. Contributions are encouraged that concern all aspects of the use of STEM - including instrument and technique development for all forms of imaging and spectroscopy and their application to in-situ analysis. Advanced applications of these approaches to solid state materials, nanostructures and biological systems are particularly welcomed.

A3 TEM Phase Contrast Imaging in Biological and Materials Science

Michael Marko, Radostin Danev

Conventional TEM phase-contrast imaging limits maximum information transfer to a narrow band of spatial frequencies. This can be avoided by in-focus imaging with a physical phase plate. The theory, construction, and practical use of phase plates will be explored. In biological cryo-TEM, high-contrast, high-resolution imaging at low electron dose is facilitated. In materials science, the combination of a physical phase plate with tunable Cs offers an unparalleled opportunity for characterization of both atomic details and larger structures. The number of laboratories exploring the use of phase-plates is growing, and this will be a timely opportunity to learn from each other.

A4 Electron Holography at the Atomic Scale and the Nanoscale

Molly McCartney, David J. Smith, Lin Zhou

Electron holography enables convenient access to the phase and amplitude of the electron wave passing through the TEM specimen, allowing both atomic-scale imaging as well as quantitative measurement of nanoscale electrostatic and magnetic fields. This symposium will consider recent advances in electron holography techniques and applications. Platform and poster presentations will include the emergence of novel approaches and instrumentation for electron holography, as well as providing an overview of latest applications to piezoelectric and ferroelectric materials, measurement of charge, magnetic nanostructures, both natural and man-made, and dopant profiling in semiconductor devices.

A5 15 Years of Focused Ion Beams at M&M

Lucille A. Giannuzzi, Keana Scott, Nicholas Antoniou

The first FIB session at M&M 2000 consisted of 20 papers and was dominated by applications of Ga+ focused ion beams for TEM specimen preparation. Since then, the use of FIB-based instruments has expanded to 3D analysis, specimen preparation for atom probe tomography and other techniques, nanomachining, and nanodeposition for inorganic materials, organic materials, and biological materials in ambient and cryo conditions. In addition, the development of new ion sources beyond LMIS to GFIS and ICPS using e.g., He+, Ne+, Xe+, and other ions have allowed unique imaging, analytical, milling and deposition capabilities while expanding usable length scales. Papers are encouraged on topics of focused ion beams including instrumentation, theory, and applications.

Cathodoluminescence (CL) and soft x-ray microanalysis provide unique high sensitivity information about defect microstructure, bonding and trace chemistry. CL is experiencing a resurgence due to improvements in instrumentation, data analysis, while soft x-ray microanalysis is a rapidly emerging field. With improvements in SDD technology and new WD based spectrometry the detection of ultra-soft x-rays (Li-Ka) is now possible. Challenges include surface preparation, detector stability and difficulties in dealing with peaks that reveal the complexity of the Density of States. CL and ultra-soft x-ray detection require a combined approach of measurement and quantum mechanical modelling to interpret both composition and structure. Contributions covering theory and applications are encouraged.

Correlative microscopy is where the same sample is analyzed using two or more techniques that typically differ in scales ranging from the macroscopic to the atomic level. The resulting combined data sets can be used for both materials and life sciences in a variety of circumstances, e.g., localization of rare events, determining if small regions are typical of the bulk, and combining imaging and analytical techniques. Examples include optical imaging before FIB specimen preparation, combined SEM and SPM and fluorescence-labeled imaging before TEM specimen preparation, among others.
