Abstract
Strikingly regular periodic intersubband photocurrent peaks are observed in a multiple quantum well (MQW) structure in which the periodic unit is a coupled double well. A phenomenological model is proposed and is used to explain the observed results. The complexity of the transport problem for a MQW structure in the physical regime studied here is discussed.Keywords
