How to eliminate spurious solution of a 30 band k.p hamiltonian?

Recently a 30 band k.p hamiltonian is being used to calculate the full zone bandstructure, see for example Richard, et al. PHYSICAL REVIEW B70, 235204 (2004). I was trying to discretize this...

The nonparabolic SE equation under effective mass is (E-U)[1+alpa(E-U)] = hbar^2k^2/2m. Does anyone have any idea or a reference on how this equation would be modified for arbitrary crystal orientation where effective mass is a full tensor?

I am looking for the eigen value part and the in-plane dispersion for this equation for a MOS structure where electrons are quantized in the z direction. Stern and Howard (PRB 1967) have a very...

What is the best technique to numerically calculate the 2D density of states from atomistic bandstructure?

Do you integrate the delta function in k-space when you have the tool/code to calculate the E-k dispersion? In other words, which one is better: (1) smearing the delta function using Gaussian or...
