gallium based semiconductors  see reference below

Reference: Properties of Ga-based semiconductors
gallium antimonide, GaSb  III-V compound semiconductor; energy gap Eg = 0.72 eV, direct; mobility of electrons and holes 5000 and 850 cm2/V-s respectively.
gallium arsenide, GaAs  III-V compound semiconductor, after silicon second the most common semiconductor, energy gap Eg = 1.43 eV, direct; crystal structure - zinc blend, lattice constant 0.565 nm, index of refraction 3.3, density 5.32 g/cm3, dielectric constant 12.9, intrinsic carrier concentration 2.1 x 106 cm-3, mobility of electrons and holes at 300 K - 8500 and 400 cm2/V-s, thermal conductivity 0.46 W/cm-oC, thermal expansion coefficient 6.86 x 10-6 1/oC; thermally unstable above 600 oC due to As evaporation; does not form sufficient quality native oxide; mechanically fragile; due to direct bandgap commonly used to fabricate light emitting devices; also foundation of the variety of high-speed electronic devices; bandgap can be readily engineered by forming ternary compounds based on GaAs, e.g. AlGaAs.
gallium phosphide, GaP  III-V compound semiconductor; energy gap Eg = 2.26 eV, indirect; mobility of electrons and holes 110 and 75 cm2/V-s.
gallium nitride, GaN  wide bandgap III-V semiconductor featuring direct bandgap 3.5 eV wide; among very few semiconductors capable of generating blue radiation; number one candidate for blue LEDs and lasers; see "GaN note" on for more information.
