Surface relief holograms in evaporated arsenic trisulfide films

Optical and electrical properties of In4Se96-xSx chalcogenide thin films

“…The optical properties of chalcogenide semiconductors changes when induced by light of appropriate energy and intensity. The properties include photoconductivity, photovoltaics, photoluminescence, and non-linear optical phenomena that are connected with purely electronic effects, furthermore photo-induced modifications which includes local expansion or contraction, modification of refractive index, change in density, hardness, chemical reactivity, optical properties as well as decomposition and crystallization has been observed [14][15][16].…”

<title>Photosensitivity of As-S-based chalcogenide photoresists in the recording of relief phase holograms</title>

“…As4S4 vapor Sfl vapor ( 1) At condensation, the significant part of molecules, having the As-As and S-S homobonds, do not recombine on a substrate surface and are being as "frozen" particles in the polymer network of AsS312 units. As a result, in thermally as-deposited films, the reaction of photostructural changes can be written as the recombination of homobonds As-As and S-S to heterobonds As-S (reverse reaction to (1)):…”

Chalcogenide glassy photoresists: History of development, properties, and applications

“…Later, the possibility of creating inorganic photoresists attracted attention of many researchers [17][18][19][20][21][22][23]. Most investigators studied and applied ChGP based on the arsenic chalcogenides, while the Japanese researchers worked with the germanium chalcogenide-based ChGP [18,19].…”
