Description

The only commercially available GaSSe alloys: Bulk Gallium sulfide selenide alloys exhibit band gaps ranging from 2.0 eV (GaSe) t0 2.6 eV (GaS) mostly covering the UV band gap ranges. Crystals are perfectly layered in the c-axis direction, comes ready for exfoliation, and crystals have an impressive environmental stability. Single crystal GaSeTe comes ready for exfoliation and is ideal for 2D research. GaSeTe alloys only come at ~50% (GaSe0.5Te0.5) alloying ratio due to phase separation phenomena taking place at other compositions.
