Valence band states in diamond p-delta-doped quantum wells

The hole energy structure in boron delta-doped diamond is studied with the use of the 6 × 6 k · p Hamiltonian. The approach starts with a Thomas-Fermi-based description of the heavy, light and split-off hole states at the Brillouin zone center, and is extended to k 6= 0 points by using the obtained Γ-point solutions as a basis for the diagonalization that leads to the energy vs k relations corresponding to the different subbands in the coupled system of valence bands. The possible use of the results of this calculation as a way to identify the actual values of the Luttinger parameters in diamond is discussed.
