SEMICONDUCTOR DEVICE INCLUDING RESONANT TUNNELING DIODE STRUCTURE HAVING A SUPERLATTICE AND RELATED METHODS

摘要

A semiconductor device may include at least one double-barrier resonant tunneling diode (DBRTD). The at least one DBRTD may include a first doped semiconductor layer and a first barrier layer on the first doped semiconductor layer and including a superlattice. The superlattice may include stacked groups of layers, each group of layers including a plurality of stacked base semiconductor monolayers defining a base semiconductor portion, and at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions. The at least one DBRTD may further include an intrinsic semiconductor layer on the first barrier layer, a second barrier layer on the intrinsic semiconductor layer, and a second doped semiconductor layer on the second superlattice layer.
