The interior of a compensated semiconductor crystal at low temperatures is pervaded by a spatially varying electrostatic potential arising from its embedded donor and acceptor ions. In a frozen-out n -type semiconductor, for example, the electrostati

Ground-state ${\mathrm{D}}^{\mathrm{\ensuremath{-}}}$ concentrations in quantum-well structures which are lightly doped in both the barriers and wells are investigated by means of computer simulation. Correlation between electrons on different sites

Solutions which are exact in the high-magnetic-field limit have recently been reported for a two-dimensional ${\mathit{D}}^{\mathrm{\ensuremath{-}}}$ problem in which the two electrons and the fixed positive ion are all confined to the x-y plane. The

Variational estimates of the energies of the lowest-lying M=-1 (p-like) and M=-2 (d-like) states of the H - ion or its analog in bulk semiconductors, the D - ion, are presented as functions of magnetic field over a wide range of field strengths. The

Low-lying singlet states of the D - center, a hydrogenic donor with a second electron attached, are studied for two-dimensional and bulk three-dimensional centers in uniform applied magnetic fields. Accurate trial functions which are, at the same tim

D - centers have been unambiguously identified in GaAs/(Ga,Al)As quantum wells by analysis of the dependence of the observed photoconductivity spectrum on the applied magnetic field and sample orientation. Theoretical investigations show that in magn

Excited states of the two-dimensional ${\mathit{D}}^{\mathrm{\ensuremath{-}}}$ center (or ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ ion) are considered in the low-field and high-field limits. It is shown that in two dimensions there are no bound analo
