Semiconductor device including a superlattice and adjacent semiconductor layer with doped regions defining a semiconductor junction

Abstract

A semiconductor device may include a superlattice comprising a plurality of stacked groups of layers. Each group of layers of the superlattice may include a plurality of stacked base silicon monolayers defining a base silicon portion and an energy band-modifying layer thereon. The energy band-modifying layer may include at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base silicon portions. The semiconductor device may further include a semiconductor layer adjacent the superlattice and comprising at least one first region therein including a first conductivity type dopant. The superlattice may also include at least one second region therein including a second conductivity type dopant to define, with the at least one first region, at least one semiconductor junction.
