   Dear Colleagues,

   The final decision on the winner(s) of the Ovshinsky Award for the year 2002, belongs to you all. If you have other suggestions, ideas, comments, or even arguments for or against the above results, please make them public by writing simultaneously to me and to the other members of the Jury, whose e-mail addresses are written (as CC) on the head of my e-mail message.


Many thanks for your efforts,


With the best wishes for enjoying the summer holidays,

Prof. Dr. Mihai Popescu


Professor Victor Lyubin was born in Sankt Petersburg (former Leningrad) in Russia (former Soviet Union) in 1928, May 4. He studied at the Physical-Mechanical Faculty of Leningrad Polytechnic Institute in the interval 1948-1952. After graduation he worked in several Russian Industrial Research Centers specialized in the field of Radar and Television. He participated in the development of many Vidicon type television tubes and proposed the application of the chalcogenide films in these devices.

   The subject of his philosophical degree thesis sustained in 1960 was "The photoconductivity of the amorphous chalcogenide films and their use in Vidicons cameras".

   In 1969 Prof. Lyubin was invited to work in "A. F. Joffe Physico-Technical Institute of the Academy of Sciences of USSR", where together with Professor Boris Timofeevich Kolomiets, started to study the interaction of light with chalcogenide glassy semiconductors and various photoelectric phenomena. One of the subjects of his researches was the "modification" of chalcogenide glassy films by various metals, then a hot subject proposed by S. R. Ovshinsky. Professor Lyubin discovered and investigated several photoinduced effects in chalcogenide glasses: photo darkening and photo-refraction induced by electronic beams, X-rays, y-rays and gas-discharge. Of great importance is the discovery by Prof. Lyubin and is co-workers, and careful investigation of the photoinduced vectoral effects in chalcogenide glasses. They studied the photo-induced dichroism and birefringence, the silver-photo-doping induced by polarized light, the photo-gyrotropy, etc.

   Part of these results is included in his thesis of Doctor of Science, confirmed in the A.F. Joffe Physico-Technical Institute in 1975. In 1991 Professor Lyubin emigrated in Israel and started his work at Physical Department of the Ben-Gurion University of the Negev. He continued the study of electronic and optical phenomena in glassy chalcogenides. He made systematic investigations of the anisotropy induced in chalcogenide glasses by light of above-band-gap, sub-band-gap and super-band-gap energy. Prof. Lyubin and his co-workers revealed the strong increase in photosensitivity of the photo-structural transformations induced by short laser pulses. They obtained and published important data on the anisotropy and gyrotropy of photo-induced light scattering in bulk chalcogenide glasses and discovered the polarization-dependent photo-crystallization and anisotropy of photoconductivity in chalcogenide films. Moreover, Prof. Lyubin revealed new peculiarities in photodoping by zinc of chalcogenie films. Professor Lyubin used his skills for applied research: finding new efficient chalcogenide photoresists and developers, and the development of new types of microlens arrays and photo-ionic band-gap structures based on chalcogenides. Professor Lyubin published more than 300 papers and registered more than 70 inventions.

   Professor Lyubin, the man, was a sportsman and played volleyball and skiing. He was a member of the volleyball team of the Leningrad Student Association. The hobby of Professor Lyubin is to collect art post-card. From his youth he was passionate for mushrooms (to search for, to store them and to prepare).



Professor Kolobov was born in Armavir, Krasnodar district of the former Soviet Union, on 10-th April 1955. He finished the secondary school in Moghilev, Bielorussia. There started his passion for physics because of a wonderful physics teacher: Victor Mateevich. In 1972 the young Sasha got the Gold Medal for excellent studies of the Ministry of Education of Russia (Soviet Union). Thereafter, the young Sasha Kolobov was admitted in the Leningrad Electrotechnical Institute. He got the basis for his future work in the Department of Optoelectronics headed by the future Nobel Prize winner for 2002, Zh. Alferov. As a third-year student Sasha Kolobov joined the "A.F. Jofe Physico-Technical Institute" in the laboratory of Prof. B. T. Kolomiets, research group of Prof. Victor Lyubin. Here he got the first acquaintance with the chalcogenide vitreous or glassy semiconductors that become a lifelong commitment.

   In 1983 Alexander Kolobov got his philosophical degree in physics and in 1992 he got the degree of Doctor in Sciences, the highest academic degree in Russia.

    Professor Alexander Kolobov worked abroad long periods of time: he was fellow of the Trinity College (UK), visiting fellow at Cambridge University (UK) (1988-1989), Kapitza fellowship awardees of the Royal Society of London (1993), and worked one year in Paris at the Ecole Superieure de Physique et Chimie Industrielle (1991-1992) and 3 months as guest professor at Katholieke Universiteit Leuven, Belgium (1993) in the frame of the program "Capita selecta".

    Starting with 1994 Professor Alexander Kolobov is senior scientist in Japan. Initially he was with the National Institute for Advanced Interdisciplinary Research and, from 2001, after re-organization of National Institutes in Japan, at the Institute of Advanced Industrial Science and Technology. He is involved in the major present research areas: chalcogen-based phase-change materials for optical memories and optical data storage. The main academic interest of Professor Kolobov are: the structure and photo-induced phenomena in amorphous semiconductors; the material modification through electronic excitation; the local structure in metallic and semiconducting nano-particles; the self-assembled nano-structures; germanium nano-crystals and quantum dots; X-ray absorption spectroscopy; Raman scattering; surface plasmons; application of synchrotron radiation to material science. Professor Kolobov used consistently the advanced experimental techniques in trying to answer the fundamental questions concerning electronic structure and photo-induced structural changes in chalcogenide glasses in general, and in selenium in particular. He elucidated the nanometer-scale mechanism of reversible photostructural changes in amorphous chalcogenides. Professor Kolobov published more than 130 original papers in refereed journals and several reviews.

   Professor Kolobov is married and has an 8-years daughter born in Japan. His hobbies are literature, history, linguistics (Japanese). He speaks fluently English, French, Japanese and German. He likes climbing the mountains and is passionate for opera and ballet.
