The electrons in inversion or accumulation layers of MOSFETs or in semiconductor-semiconductor interfaces show prominent many-body effects. A new theory off the correlation energy is developed for these electrons such that the results are applicable

In the present paper we determine the oscillator strength of two-dimensional (2D) D − ions under the influence of a static magnetic field. The results are important for the analysis of the optical transitions observed in semiconductor quantum wells

We have used the adiabatic hyperspherical approach to determine the energies and wavefunctions of the ground state and first excited states of a two-dimensional D- ion in the presence of a magnetic field. Using a modified hyperspherical angular varia

Fano-like interferences between electronic and LO-vibronic inelastic light scattering are reported for periodic GaAs doping multilayers at room temperatures as a function of the orientation of the sample crystallographic axes relative to the linear p

Theoretical calculations for the resonant Raman spectra of spin-density transitions elucidating the influence of hole states participating in the resonance scattering process as well as a continuum of intersubband transitions are reported for periodi

The asymmetry in the one-phonon Raman lines of a Si:GaAs δ-doped doping superlattice is interpreted as a quantum-mechanical interference process in which an incident photon is inelastically scattered by a resonance excitation composed of a bulk LO o

We have investigated the effects of Coulomb interactions in a two-dimensional array of quantum dots subjected to lateral harmonic confinement. Coulomb coupling among dots is manifested in the spectrum of collective modes through the wavevector depend

A simple electromechanical analog for Landau’s classical theory of second‐order symmetry‐breaking transitions is presented. The apparatus consists of a torsion pendulum, where a ceramic magnet suspended by two torsion springs is subjected to a

As it is known [1] an intense laser field can induce atom-atom interaction according to a dipole-dipole R−3 law. Such an interaction depends on the angle between light polarization and interatomic vector-position R. This angular dependence may prod
