Gallium antimonide

It has a room temperature lattice constant of about 0.610 nm.

[1] It has a room temperature direct bandgap of approximately 0.73 eV.

[1][2][3] The intermetallic compound GaSb was first prepared in 1926 by Victor Goldschmidt, who directly combined the elements under an inert gas atmosphere and reported on GaSb's lattice constant, which has since been revised.

[4] The Ga-Sb phase equilibria was investigated in 1955 by Koster[5] and by Greenfield.

[6] GaSb can be used for Infrared detectors, infrared LEDs and lasers and transistors, and thermophotovoltaic systems.

NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
