CHALCOGENIDES - ALEXANDER V KOLOBOV JUNJI TOMIN...

A state-of-the-art description of photo-induced effects observed in amorphous chalcogenides is
presented with the accent on the underlying physics. A comparison is made between
sulphur(selenium)-based chalcogenides where numerous photo-induced phenomena take place
entirely within the amorphous phase and tellurides where a crystal-to-amorphous phase-change is
a major effect and correlations between various phenomena and structure and glass-forming
ability are discussed. Applications of photo-induced metastability in devices - present and
upcoming optical memories among others - are discussed  while  to orient the reader  the
various disc formats are described. Background material essential for understanding current
research in the field is also provided.
