ABOUT THE COURSE INSTRUCTOR:
PROFESSOR STAN VEPREK
After his initial research work in plasma diagnostics and spectroscopy, Stan Veprek began his work on the deposition of thin films by means of plasma CVD 40 years ago at the Institute of Physics of the Czech Academy of Science where he started his scientific career after an education as a high school teacher (in Ceske Budejovice) followed by the study of physics at the Charles University in Prague (graduated 1962). His first major result was the deposition of nanocrystalline silicon, nc-Si, by means of chemical transport in plasma (published in 1968; nowadays, nc-Si is an important material for large-scale microelectronics, flat panel displays and thin films solar cells). He became involved in the research of the plasma-wall interactions in nuclear fusion devices. In 1976 he proposed the protective coating of the inner wall with boron carbide, and in the following years developed "boronization" by means of plasma CVD, which found successful application in several large fusion devices around the world.
His continuing interest in nc-Si resulted in, among others, classical papers on Raman scattering. Together with the Swiss national museum he developed a new plasma-chemical method for the restoration and conservation of archeological metallic artifacts.
Stan has published 368 papers and several book-chapters. The most recent book co-authored with Prof. C. Koch, I. Ovidko and S. Seal “Structural Nanocrystalline Materials” (Cambridge University Press 2007). He is co-editor of Plasma Chemistry and Plasma Processing, and has co-organized various conferences and sessions at ISPC, MRS, ICMCTF and others, and served on several IUPAC and Int. Union of Vacuum Societies committees.
He received the Silver Medal of the Societe d’Encouragement Pour la Recherche et l’Invention, Paris (1979), Silver Medal of the Masaryk University Brno (1991), Honorary Doctorate (Dr. h.c.) from the Masaryk University Brno, Czech Republic (1999), the Blaise Pascal Medal of the European Academy of Sciences (2004) and the AVS John Thornton Memorial Award of the American Vacuum Society (2005). In 2003 he was appointed foreign member of the Commission I of Low-Temperature Plasma Chemistry, Polish Academy of Sciences, Branch Lublin.
