摘要：
An inverse parabolic quantum well was successfully grown by molecular-beam epitaxy using a digital compositional grading superlattice composed of Al0.36Ga0.64As/GaAs. The photoluminescence and photocurrent measurements for this structure gave a good agreement between experimental and theoretical results. Large Stark shift and amplitude reduction of 1e-1hh exciton resonance under applied electric field were found in the photoluminescence spectra, which are substantially larger than the conventional square quantum well. These properties benefited from the concept of local-to-global state transitions.
