Contactless electroreflectance and theoretical studies of band gap and spin-orbit splitting in InP1-xBix dilute bismide with x <= 0.034
Artikel i vetenskaplig tidskrift, 2014

Contactless electroreflectance is applied to study the band gap (E-0) and spin-orbit splitting (Delta(SO)) in InP1-xBix alloys with 0 < x <= 0.034. The E-0 transition shifts to longer wavelengths very significantly (-83 meV/% Bi), while the E0 + Delta(SO) transition shifts very weakly (-13 meV/% Bi) with the rise of Bi concentration. These changes in energies of optical transitions are discussed in the context of the valence band anticrossing model and ab initio calculations. Shifts of E-0 and E-0 + Delta(SO) transitions, obtained within ab-initio calculations, are -106 and -20 meV per % Bi, respectively, which is in a good agreement with experimental results.
