Quasi two-dimensional electron-hole systems in a perpendicular magnetic field
Abstract
The electronic properties of quasi two-dimensional multicomponent systems are investigated in the presence of a perpendicular magnetic field. The effects of the presence of a few valence band holes on the properties of quantum Hall systems are examined by analyzing the results of exact numerical diagonalization of small electron-hole systems confined to the spherical surface. The novel type of elementary excitations, the angular momenta, binding energies, interaction pseudopotentials, and effects on the photoluminescence spectrum are presented.
