Energy‐Dependent Connection Rules of Envelope Functions at Heterointerfaces

Abstract

It is shown that the energy-dependent connection rule of Bastard can be derived in a simple manner. The method can be generalized to more general ones than the Kane band structure. Moreover, starting from a complete two-band model a classification of different former approaches of connection rules is presented and that one of Ishibashi et al. is derived with less restrictions and in a simple way. It is shown that the use of the two-band model modifies the tunneling probability as it is usually calculated from a one-component description.
