Valley degeneracy in biaxially strained aluminum arsenide quantum wells
Valley degeneracy in biaxially strained aluminum arsenide quantum wells
This paper describes a complete analytical formalism for calculating electron subband energy and degeneracy in strained multivalley quantum wells grown along any orientation with explicit results for AlAs quantum wells (QWs). In analogy to the spin index, the valley degree of freedom is justified as a pseudospin index due to …
