Abstract
The mechanism of photoinduced expansion/contraction in glassy As2S3 has a photochemical nature. Photostructural transformation is connected with rearrangement of As4S4 molecules and similar non-stoichiometric compounds, As4S4+x. These molecules are believed to exist in clusters which correspond to the second glass-forming region of As–S systems, including the As56S44 eutectic. [ABSTRACT FROM AUTHOR]
