Abstract

A method for making an electronic device may include forming a selectively polable superlattice comprising a plurality of stacked groups of layers. Each group of layers of the selectively polable superlattice may include a plurality of stacked semiconductor monolayers defining a semiconductor base portion and at least one non-semiconductor monolayer thereon. The at least one non-semiconductor monolayer may be constrained within a crystal lattice of adjacent silicon portions, and at least some semiconductor atoms from opposing base semiconductor portions may be chemically bound together through the at least one non-semiconductor monolayer therebetween. The method may further include coupling at least one electrode to the selectively polable superlattice for selective poling thereof.
