SEMICONDUCTOR DEVICE INCLUDING A SUPERLATTICE HAVING AT LEAST ONE GROUP OF SUBSTANTIALLY UNDOPED LAYER

摘要

A semiconductor device includes a superlattice that, in turn, includes a plurality of stacked groups of layers. Each group of the superlattice may include a plurality of stacked base semiconductor monolayers defining a base semiconductor portion and an energy band-modifying layer thereon. Moreover, the energy-band modifying layer may include at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions. At least one group of layers of the superlattice may be substantially undoped.
