Dresselhaus effect in bulk wurtzite materials Available to Purchase

The spin-splitting energies of the conduction band for ideal wurtzite materials are calculated within the nearest-neighbor tight-binding method. It is found that ideal wurtzite bulk inversion asymmetry yields not only a spin-degenerate line (along the $kz$ axis) but also a minimum-spin-splitting surface, which can be regarded as a spin-degenerate surface in the form of $bkz2−k‖2=0$ $(b≈4)$ near the $Γ$ point. This phenomenon is referred to as the Dresselhaus effect (defined as the cubic-in-$k$ term) in bulk wurtzite materials because it generates a term $γwz(bkz2−k‖2)(σxky−σykx)$ in the two-band $k∙p$ Hamiltonian.
