AbstractApplication of moderate external electric fields to ZnSe/(Zn,Mn)Se superlattices is shown to yield readily measurable spectral shifts of the exciton ground state resonance in the quantum well limit. This shows that confinement effects increase the classical field ionization threshold. At high applied fields and low temperatures, externally injected hot electron excited luminescence from internal excitations of the Mn-ion is observed.

A Monte Carlo study of hot-electron intrinsic noise in a n-type GaAs bulk driven by one or two mixed cyclostationary electric fields is presented. The noise properties are investigated by computing the spectral density of velocity fluctuations. An analysis of the noise features as a function of the amplitudes and frequencies of two applied fields is presented. Numerical results show that it is possible to reduce the intrinsic noise. The best conditions to realize this effect are discussed.

Static Dielectric Constants

Dielectric properties of α-quartz and rutile-GeO2 thin-films are investigated using first-principles ground-state calculations in external electric fields. The optical and the static dielectric constants inside the films have nearly-constant values, corresponding to their bulk values, while only at the topmost surface layer the dielectric constants decrease distinctly. It has been found that the dielectric constant for the rutile-GeO2 is larger than that for the α-quartz one, which stems from the larger ionic character of the Ge-O bond for the rutile phase.
