本文报道了GaSb在${ensuremath{Gamma}}_{8}^{v}ensuremath{-}{ensuremath{Gamma}}_{6}^{c}$直接跃迁和${ensuremath{Gamma}}_{8}^{v}ensuremath{-}{L}_{6}^{c}$间接跃迁附近的电反射光谱。30 K的$ {L} _ {6} ^ {c} ensuremath {-} {ensuremath{伽马}}_ {6}^ {c} $差距是0.063 eV。线性区域${L}_{6}^{c}ensuremath{-}{ensuremath{Gamma}}_{6}^{c}$间隙的温度变化为-1.8ifmmode imeselse exttimesfi{}${10}^{ensuremath{-}4}$eV/${mathm {K}}^{ensuremath{-}1}$。
Electroreflectance spectra are reported for GaSb near the ${ensuremath{Gamma}}_{8}^{v}ensuremath{-}{ensuremath{Gamma}}_{6}^{c}$ direct transition and the ${ensuremath{Gamma}}_{8}^{v}ensuremath{-}{L}_{6}^{c}$ indirect transition. At 30 K the ${L}_{6}^{c}ensuremath{-}{ensuremath{Gamma}}_{6}^{c}$ gap is 0.063 eV. The temperature variation of the ${L}_{6}^{c}ensuremath{-}{ensuremath{Gamma}}_{6}^{c}$ gap in the linear region is of the order of -1.8ifmmode imeselse exttimesfi{}${10}^{ensuremath{-}4}$eV/${mathrm{K}}^{ensuremath{-}1}$.
