摘要:

We report the use of wavelength‐modulated photocurrent spectroscopy to obtain detailed information on quantum well transitions in an In0.14Ga0.86As/GaAs strained‐layer superlattice. The spectra are interpreted in terms of a Kronig–Penney model with literature values for offsets and deformation potentials. The effect of the test structure’s built‐in electric field must be included to obtain agreement with this theory.
