Dr.-Ing. Hans J. Scheel

Starting out with a chemical background, he has more than 40 years of experience with crystal growth technology and epitaxy in universities as well as in chemical industry, machine industry, and electronic/computer industry. For his achievements in bulk crystal growth and epitaxy technologies, he received awards from IBM and from Swiss, British, Korean Crystal Growth Associations, was elected member of the Russian Academy of Engineering Sciences, received his D.Sc. from Tohoku University, Japan, and was full professor at the University of Sao Paulo and lecturer at the National Space Research Institute INPE in Sao Jose dos Campos, Brazil. He is co-author and editor of 6 books and author of more than 100 publications and patents.
After retiring from the Swiss Federal Institute of Technology in 2001 Hans J. Scheel was visiting professor at Osaka University & Tohoku University, Japan and Shandong University, China.
Recent activities include history of crystal growth, education of crystal technologists for developing optimum technologies for energy saving and renewable energy devices, in a high-safety airliner, and large-scale fluid dynamics problems like tsunamis and tropical storms.
In December 2017 HJS started the company «General Protection Engineering GmbH» and is looking for partner, see

About this Website

This website is dedicated to the life and work of Dr.-Ing. Hans J. Scheel as a researcher and inventor in the field of Crystal Growth Technology (CGT). It should pass long-year experiences to the younger generation and motivate education of crystal technologists and crystal growers in the multi-disciplinary field of CGT including deriving single optimum technologies for producing best specific crystals, epilayers, and multilayers.

Result of first ACRT experiment January 1970: a 210g GdAlO3 crystal
