Name: Gallium Selenide (GaSe) (2H phase)
SKU: ACM12024112-3
Rating: 5 (1 reviews)

Description

Description GaSe (2H phase) is a semiconductor with an indirect band gap of about 2.1 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. GaSe belongs to group 13 late transition metal monochalcogenides.

Features And Benefits

Features And Benefits The 2H phase of Gallium Selenide has a typical lateral size of ~0.6-0.8 cm and has a dark-copper metallic appearance.

Application

Application GaSe has been used as semiconductors, photoconductors, second-harmonic generating crystals in nonlinear optics, and far-infrared conversion materials.
