Abstract: The electronic band structure of wurtzite semiconductor heterostructures is investigated theoretically using the envelope function k·P formalism. We use a Lagrangian formulation for the valence bands so that the order of the derivatives appearing in the multiband description is explicitly specified when Schrödinger's equations for the envelope functions are generated through the application of the principle of least action. The issues of derivative operator ordering and boundary conditions at material interfa…
