Spin-orbit splitting in diamond: Excitons and acceptor related states

Abstract:

The spin-orbit splitting Δ<inf>0</inf> = 13 meV calculated ab initio for the Γ<inf>8</inf>⁺ valence band state of diamond differs from that observed for acceptors (≈2 meV) and exciton states (≈7 = meV). A full-zone k-p band structure, together with a Slater-Koster attractive potential, is used to explain these differences and thus clarify the contradictory assignments of spin-orbit splittings found in the literature for diamond.
