In the first part of the year 2001 I had discussions with Prof. Radu Grigorovici and Stanford R. Ovshinsky in order to create an Award for Excellence in Amorphous Semiconductors. Stan promised to support partially the Award, to become later a Prize in the field of chalcogenides.
The first Award in the chalcogenide field of research was conferred during the first International Workshop on Amorphous and Nanostructured Chalcogenides (ANC-1) held in Bucharest in June 2001. At this workshop Prof. Radu Grigorovici handed the diploma of the Award to the first winners: Profs. Keiji Tanaka and Stephen R. Elliott.
Starting from 2005 the Award has been transformed into a Prize; the amount of this Prize increased stepwise from 500 USD (2005) to 2000 USD in 2009 and 2010.
The Ovshinsky Prize honours a bunch of highest best specialists in the field of amorphous chalcogenides in both science and technology.
In 2009 we have been honoured with the presence of Stanford Ovshinsky at the 4th edition of the Workshop of Amorphous Chalcogenides (ANC-4), which became the International Conference on Chalcogenides. At that time Stan received the title of Doctor Honoris Causa of the University of Constanta (Romania) where the ANC-4 was held.
The Internet address of the Prize can be found on the Forum of Chalcogeniders: http://www.chalcogen.infim.ro.
The list of the winners of the Ovshinsky Prize is given in Table 1.
