Abstract
Using a combination of experimental and theoretical techniques we present the dependence of the bandgap Eg and the spin orbit splitting energy Δso, with Bi concentration in GaAsBi/GaAs samples. We find that the concentration at which Δso,> Eg occurs at 9%. Both spectroscopic as well as first device results indicate a type I alignment.
