# Formula Energy band gap of GaAs (temperature dependence)

## Energy band gap

`\( E_{\text g} \)`Unit

`\( \text{eV} \)`

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 \(E_{\text g}\) |
---|---|

0 K | 1.522 eV |

300 K | 1.435 eV |

1000 K | 1.076 eV |

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

## Temperature

`\( T \)`Unit

`\( \text{K} \)`

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