Fast Coherent Vertical Exciton Transport in Multiple Quantum Wells

Not Accessible

Your library or personal account may give you access

Abstract

In superlattices in which the barriers are sufficiently narrow and low, the low-temperature vertical transport of excitons is due to quantum-mechanical tunneling between successive quantum wells (QW).[1] For structures with wide and high barriers [multiple QW’s (MQW)], the interwell coupling is due to the dipole-dipole interaction.[2] The context for treating coherent effects of this sort is exciton-polariton theory.[3] Exciton transport has been of interest in various molecular systems,[4] where the picture is of incoherent Förster transport.[5]. The MQW provides a tailor-made system of which an individual structure can be studied, while data on molecular systems must be frequently interpreted in terms of ensembles. There has been little experimental or theoretical[6] work on this type of vertical transport in MQW’s, although incoherent transport in such structures has been the subject of one study.[7]
