Paper Abstract

For analytical description of multiple quantum well superlattices (MQW) main characteristics, for example, current-voltage characteristic (CVC), of the model of well with rectangular and symmetric walls is usually used. However, deviation of experimental characteristics of real MQW from analytical dependence make it possible to suppose, that real MQW are not rectangular and even not symmetric. The study of nonrectangular well influence on MQW characteristics would make it possible to determine how prevent from this influence by means of some modification introduction into growth process. In this report we present analytical description of CVC, field dependence of responsivity and signal/noise ratio for nonrectangular MQW. Analytical results are compared with experimental data. The possible ways to compensate nonrectangular wells influence is considered.
