Stanford R. Ovshinsky Prize for Excellence in Amorphous Chalcogenides

Authors


Abstract

The short history of the Ovshinsky Prize conferred for Excellence in Amorphous Chalcogenides is presented.

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.

For improvement of ab initio modelling of chalcogenides and for developing models of rigidity for phase-change materials leading to the rigidity phase diagram in GST materials. This work should open a new perspective enabling the study of phase-change materials in much the same fashion as network glasses.

For discovery of the rapid reversible phase-change phenomenon between amorphous and metastable cubic phases of GeTe–Sb2Te3 pseudo-binary alloys and for developing phase-change optical disks including new technologies for material compositions and device structures.

The next prestigious Prize will be awarded in 2013 during the 6th edition of the International Conference on Amorphous and Nanostructured Chalcogenides (ANC-6).
