Atomic structure of mercury chalcohalide glasses
Optical applications of chalcogenide glasses need a wide transparency window in far IR. Promising glass systems include HgI2. We have synthesised three vitreous systems... -
Mercury Sulphide Dimorphism in Thiogermanate Glasses
Crystalline mercury sulphide exists in two drastically different polymorphic forms: red chain-like insulator, alpha-HgS, and black tetrahedral narrow-band semiconductor,...
