Abstract

A bipolar junction transistor (BJT) may include a substrate defining a collector region therein. A first superlattice may be on the substrate including a plurality of stacked groups of first layers, with each group of first layers including a first plurality of stacked base semiconductor monolayers defining a first base semiconductor portion, and at least one first non-semiconductor monolayer constrained within a crystal lattice of adjacent first base semiconductor portions. Furthermore, a base may be on the first superlattice, and a second superlattice may be on the base including a second plurality of stacked groups of second layers, with each group of second layers including a plurality of stacked base semiconductor monolayers defining a second base semiconductor portion, and at least one second non-semiconductor monolayer constrained within a crystal lattice of adjacent second base semiconductor portions. An emitter may be on the second superlattice.
