Abstract

We have independently estimated the conduction- and valence-band offsets ΔE_c and ΔE_v in GaAs/Ga_0.51In _0.49P quantum wells by measuring the capacitance transient resulting from thermal emission of carriers from the respective wells. The heterostructure samples were grown by low-pressure metalorganic chemical vapor deposition. The band offsets are extrapolated from the emission activation energies with appropriate corrections. The estimated values of ΔE_c and ΔE_v are 0.198 and 0.285 eV, respectively.
