Abstract

Photoreflectance was used to study lattice-matched Ga_0.5In_0.5P/GaAs heterostructures grown using metalorganic chemical vapor deposition. The built-in electric field in the GaAs region at the Ga_0.5In_0.5P/GaAs interface was evaluated using the observed Franz-Keldysh oscillations. The fundamental energy gaps, E_o and E_o+Δ_o, of Ga_0.5In_0.5P were also determined. In addition, we found that as the doping concentration of the Ga_0.5In_0.5P increased, the broadening parameters of the band gap also increased.
