Inter-Valence-Band Hot Hole Laser in Two-Dimensional Delta-Doped Homoepitaxial Semiconductor Structures

Hole spin dynamics and valence-band spin excitations in two-dimensional hole systems

In recent years, the spin dynamics and spin–orbit interaction in GaAs-based two-dimensional hole systems (2DHS) have created a lot of attention. This is due to the complex structure of the valence band, with its p-like character, which leads to strong spin–orbit coupling. In this paper, we review our recent studies on hole spin dynamics and valence-band spin excitations in GaAs-based, p-modulat...

Inter-valence-band hole-hole scattering in cubic semiconductors

Transitions between valence subbands resulting from hole-hole scattering in cubic semiconductors have been analyzed in the frame of Coulomb interaction of valence electrons in the Luttinger-Kohn representation. Expressions for transition rates are derived. Calculated rates for transitions between lightand heavy-hole bands are presented for germanium. Hole-hole scattering has remarkably differen...

Spectroscopic ellipsometry of homoepitaxial diamond multilayers and delta-doped structures

Dielectric function model for p-type semiconductor inter-valence band transitions

The contributions of inter-valence band (IVB) transitions to the dielectric function (DF) by free holes among the split-off (so), light-hole (lh) and heavy-hole (hh) bands were investigated. A model was developed to determine the DF of two p-type semiconductors, GaAs and Ge1 ySny with the Zinc-blend and Diamond crystal structures, respectively. The IVB transitions dominate the spectral range be...

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 corr...
