Abstract: We investigated the feasibility of directly estimating split-off hole effective mass m so from Franz–Keldysh oscillations using non-destructive and non-invasive photoreflectance spectroscopy. We used an undoped/n-type GaAs epitaxial structure and two GaAs p–i–n diode structures.… read more here.
