摘要：
Oblique‐incidence reflectance and photoreflectance of heterostructures near the resonance frequencies of excitons confined in a single quantum well are studied. Under illumination with above barrier band gap light at low temperature, the relative change ΔR/R of the reflectivity is found to reach 10% and even more. The experimental results can be explained by a photo‐induced decrease in the exciton damping and attributed to neutralization of the barrier impurity centres under the illumination.
