摘要：

We present a detailed generalization of the Franz-Keldysh theory of electromodulation which takes into account the presence of a dc surface electric field, scrEdcs. We demonstrate rigorously that when the ac modulating electric field is small compared to scrEdcs, the period of the Franz-Keldysh oscillations yields scrEdcs. This result is independent of the relation between the width of the space-charge region and the penetration depth of light. The effects of broadening also are considered. © 1990 The American Physical Society.
