Giant bowing of the band gap and spin-orbit splitting energy in GaP(1−x)Bi(x) dilute bismide alloys
Using spectroscopic ellipsometry measurements on GaP(1−x)Bi(x)/GaP epitaxial layers up to x = 3.7% we observe a giant bowing of the direct band gap ([Formula: see text] ) and valence band spin-orbit splitting energy (Δ(SO)). [Formula: see text] (Δ(SO)) is measured to decrease (increase) by approxima...
