Abstract

Electroreflectance spectra are reported for GaSb near the

Γ_{8}^{v} - Γ_{6}^{c}

direct transition and the

Γ_{8}^{v} - L_{6}^{c}

indirect transition. At 30 K the

L_{6}^{c} - Γ_{6}^{c}

gap is 0.063 eV. The temperature variation of the

L_{6}^{c} - Γ_{6}^{c}

gap in the linear region is of the order of -1.8×

10^{- 4}

eV/

K^{- 1}

.
