Exact Envelope Function Equations for Microstructures and the Particle in a Box Model
An exact formulation of the envelope function method recently published by the author is extended to include spin orbit interaction, nonlocal microscopic potentials and nonlatticematched structures. A systematic derivation of the particle in a box model is outlined. It is also shown how the basic ideas behind the envelope function method can lead to an intuitive derivation of the particle in a box model without ambiguities concerning boundary conditions.
