Abstract
Γ-point hole states in boron δ-doped diamond quantum wells are calculated with the use of a local density Thomas–Fermi–Dirac approximation for the potential energy function and the solution of an effective mass equation. The approach includes Hartree and exchange contributions in the hole gas. The calculation assumes a two-independent (hh + lh) hole band model, and different sets of Luttinger parameters for diamond, reported in the literature, are used. It is shown that the hole spectrum is highly sensitive to the values of the valence effective masses. The results for the hole energy states would help to clarify the actual set of valence band parameters if measurements of optical absorption involving transitions from hole energy states in diamond systems with delta doping are performed.
