Dr. Paul G. Coleman简介:
Professor Paul Coleman has performed pioneering experimental research into near-surface vacancy-type defects in semiconductors using slow positron beams since the early days of the field, working at University College London, The University of Texas at Arlington, The University of East Anglia and the University of Bath. In recent years he has collaborated on an increasing number of projects with researchers from many UK and overseas institutions and companies, and is currently visit co-ordinator for EU FP6 project CADRES. EPSRC-supported research on defects created by ion implantation led to the design and construction of a positron defect spectrometer for wider application in academia and industry. Recent funded research has focused on the electrical and structural properties of thin high-k oxide films and the development of a spin-polarised positron beam for probing magnetic structures. Prof. Coleman has published 168 journal papers and reviews and over 60 conference papers. He has co-organised five international conferences and served on advisory and programme committees of fourteen others. He edited and contributed to the book Positron Beams and their Applications and recently contributed a chapter on Positron Spectroscopy to the Wiley Encyclopedia of Applied Spectroscopy.
Five examples of his research are to be found in the following papers:
