Claim 0:
1. A method for making a bipolar junction transistor (BJT) comprising:
forming a superlattice on a substrate, the substrate comprising silicon and the substrate defining a collector region therein, the superlattice comprising a plurality of stacked groups of first layers, each group of first layers comprising 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, the base semiconductor monolayers comprising silicon monolayers, and the at least one non-semiconductor monolayer comprising oxygen;
forming a base on the superlattice, the base comprising silicon; and
forming an emitter on the base, the emitter comprising silicon.
