Gallium (II) Selenide (GaSe) (CAS 12024-11-2) Description

Gallium (II) Selenide (GaSe) (CAS 12024-11-2) is a semiconductor with an indirect bandgap of ~2.1 eV. It has a hexagonal layer structure, similar to that of GaS. It is a photoconductor, a second harmonic generation crystal in nonlinear optics, and has been used as a far-infrared conversion material at 14–31 THz and above.

Applications

Gallium (II) Selenide (GaSe) (CAS 12024-11-2) crystals show great promise as a nonlinear optical material and photoconductor. Non-linear optical materials are used in the frequency conversion of laser light. One original problem with using gallium selenide in optics is that it is easily broken along cleavage lines and thus it can be hard to cut for practical application.

It has been found, however, that doping the crystals with indium greatly enhances their structural strength and makes their application much more practical. Single layers of gallium selenide are dynamically stable two-dimensional semiconductors, in which the valence band has an inverted Mexican-hat shape, leading to a Lifshitz transition as the hole-doping is increased
