Abstract Heavy, light, and split‐off hole states in single and double p‐ δ ‐doped diamond quantum wells are studied with the use of a 6 × 6 k · p model. The effective mass Hamiltonian is solved using a local density Thomas‐Fermi‐Dirac approximation for the description of the band bending pro.le. The features of the valence band spectrum are brie.y discussed in both cases. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
