# Formula Energy Band Gap of GaAs (Temperature Dependence)

## Energy band gap

Unit
Energy band gap of gallium arsenide (GaAs), that is, the energy gap between the valence band maximum and conduction band minimum..
Temperature $$T$$Energy gap $$W_{\text g}$$
0 K1.522 eV
300 K1.435 eV
1000 K1.076 eV
Bandgap of GaAs for three different temperatures.

This formula for the temperature dependence of the band gap is an experimental fit.

## Temperature

Unit
Temperature of the GaAs material in Kelvin. The band gap increases linearly with temperature.
