Multiband Quantum Transmitting Boundary Method for Non-orthogonal Basis
1998
We generalize the Multiband Quantum Transmitting Boundary Method (MQTBM) for
computing transmission coefficients in heterostructure to tight-binding-like band
structure models with non-orthogonal basis and multiple neighbor interactions. We
implement this method based on the newly developed planar-basis pseudopotential
method which uses the generalized planar Wannier function basis. We demonstrate the
method by computing transmission coefficients for a GaAs/AlAs double barrier
structure.
