Abstract
An apparatus includes a primary planar quantum well and a planar distribution of dopant atoms. The primary planar quantum well is formed by a lower barrier layer, a central well layer on the lower barrier layer, and an upper barrier layer on the central well layer. Each of the layers is a semiconductor layer. One of the barrier layers has a secondary planar quantum well and is located between the planar distribution of dopant atoms and the central well layer. The primary planar quantum well may be undoped or substantially undoped, e.g., intrinsic semiconductor.
