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...
