Abstract

In_0.53Ga_0.47As/In_0.52Al_0.48As multi-quantum well structures were studied with photocurrent spectroscopy. Based on the envelope function model in the effective mass approximation, effective mass and valence band offset were derived from the experimental eigen energies. The effective masses of the heavy hole and the light hole were 0.39 m₀ and 0.051 m₀ in a direction normal to the MQWs plane. The valence band offset was 0.22 eV. Luttinger parameters calculated from the effective masses were (gamma) ₁ equals 11 and (gamma) ₂ equals 4.3. The effective masses in the direction parallel estimated from the Luttinger parameters were 0.065 m₀ and 0.14 m₀. The parallel mass of the heavy hole estimated by this experiment agreed to the one by cyclotron resonance, 0.061 m₀.
