Valence band states in boron delta-doped diamond systems

摘要

Valence band (hh and lh) states in B delta-doped diamond quantum wells are calculated within the effective mass approximation using a local density Thomas-Fermi approximation for the description of the band bending profile. Many-body Hartree, exchange and correlation terms are included in the potential energy well function. The diagonalization of the Kohn-Luttinger Hamiltonian is performed using different sets of Luttinger parameters for diamond reported in the literature. The results could be useful in identifying the actual valence band structure of diamond.
