Abstract

The electronic states of a short asymmetric GaAs/AlAs superlattice have been studied by monitoring the optical transitions involving the superlattice resonances of such a structure embedded in a GaAs p-n junction. Three electroluminescence features arise which involve the superlattice states, one very strongly dependent on the bias applied to the p-n junction. The intensity of the emission involving superlattice states increases relative to that from the bulk when a region of negative differential resistance in the I-V characteristic is crossed. Photoconductivity measurements show four main features, three of which can be associated with the emission. Field dependences of these transitions are presented, and some initial conclusions drawn concerning the nature of the electronic states involved.
