All You Can Eat - A Menu for Scanning Electron Microscopy

Date: 20 Mar 2009 - 20 Mar 2009

Venue: SIMTech Auditorium, Tower Block, Level 3

Scanning Electron Microscopes (SEM) became commercially available instruments in the mid-sixties. Since then, they have been developed to be the most important microscope for today's research and development. There are various factors contributing to this success such as large versatility, huge range of magnification, and ease-of-use. Significantly, many special additions to the basic instrument have made it not only a simple imaging system but also a sophisticated experimental system.

This session examines the significant features of the electron emitter, the electron optical column, and the specimen chamber, particularly the so-called environmental chamber. Here the speaker will explain some important issues, including energy dispersive X-ray spectrometer, electron backscatter diffraction detector, focused ion beam attachment, and quadrupole mass spectrometer. Following these instrumentation issues, emphasis is given to the sample, its preparation, and its in-situ modification and treatment such as applying electrical current or heat, in order to gain the information wanted. Applications will be shown for metals, semiconductor, ceramics, polymers, biological and aqueous samples.

About the Speaker
Dr Ludwig Josef Balk is Full Professor for Electronics and Executive Director of the Institute of Polymer Technology of Wuppertal University in Germany. He holds a PhD from Technical University of Aachen in Germany. His professional experience and background represents a unique blend: as a prominent educator, conference keynote speaker, conference chair, seminar leader, author and member of several international journal boards. Over the period from 1993 to 1995, he was appointed Vice Dean and from 1995 to 2002, he was Dean of the Faculty of Electrical and Information engineering, Wuppertal University. He was Distinguished Visiting Professor of the Department of Electrical and Computer Engineering, National University of Singapore. He is the recipient of numerous awards with over 200 publications, of which more than 50 were invited and keynote papers. He holds 7 international patents. 

A Fellow of the Institute of Physics (Chartered Physicist) since 1999, Prof Balk's main research interest are in the areas of developing new techniques for the analysis of materials and the diagnostics of devices with micro- and nano-metre resolution and their applications. These range from pure electronic materials and devices to inorganics like functional ceramics, organic materials and devices, and biological materials such as human tissues and cells.
