摘要：

We investigate fine structure in energy derivative reflectance (EDR) spectra near 20-21 eV in GaP, GaAs, and GaSb, and near 18-20 eV in InP, InAs, and InSb. Derived energy values for Xc1 thresholds in GaP and GaSb, and Lc1 and Xc1 thresholds in GaAs, agree well with previous Schottky barrier electroreflectance (ER) results. L-X structure splittings in EDR spectra of InAs and InSb, for which Schottky barrier ER measurements cannot be performed, are 0.29 and 0.44 eV, respectively. Estimates of expected locations of these structures, based on XPS and absorption data and band structure calculations, indicate energy deficits of 0.2 eV for In4d-Lc1 and 0.5 eV for In4d-Xc1 transitions, respectively. © 1979.
