The effect of high-κ dielectric mismatch on the impurity states screened by free electron gas
is investigated theoretically in high-κ dielectric barrier/quantum well/high-κ dielectric barrier …

Abstract We use the Singwi-Sjölander-Tosi-Land (SSTL) approximation to investigate the
short-range correlations in a one-dimensional electron gas. We find out that the SSTL …

We study screening effects of a three-and two-dimensional charged Bose condensate on the
binding energy of a hydrogenic impurity. Many-body effects are taken into account via a …

The results showed that there was a parallelism between participants' perceptions and aims
of Information Technologies Certificate Program. It was revealed that the courses in the …

The Singwi-Sjölander-Tosi-Land (SSTL) approach is generalized to study the spin-
correlation effects in a one-dimensional (1D) electron gas. It is shown that the SSTL …

A many-flavor electron gas (MFEG) in a semiconductor with a valley degeneracy ranging
between 6 and 24 was analyzed using diffusion Monte Carlo (DMC) calculations. The DMC …

This thesis describes work done between October 2006 and April 2009 in the Theory of
Condensed Matter (TCM) group at the Cavendish Laboratory, Cambridge, under the …

We study the effects of screening on the binding energy of positively and negatively charged
impurities in the quasi‐one‐dimensional electron gas. We assume a parabolic confinement …
