Calculation of electron propagation in heterostructures

Analytical and numerical methods in the theory of quantum-mechanical propagation of electrons in parallel-geometry heterostructures, allowing for inhomogeneous effective mass and including interfaces, are presented: An algorithm for numerical computation of transmission probability, a treatment of the residual reflection probability in a graded structure, a discussion of resonant tunneling, and a general quantum-mechanical formulation of tunneling theory. © 1986.
