The effects of the intense laser field on donor impurities in a cylindrical quantum dot under the electric field

2011

Abstract For different nitrogen and indium concentrations, intense laser field (ILF) effect on donor impurity binding energy in a cylindrical Ga x In 1 − x N y As 1 − y / GaAs quantum dot (QD) has been studied. Results show that ILF creates an additional confinement on the electronic and impurity states in QD and increases nitrogen and indium concentration effects on electronic states.

Colle-Salvetti-type local density functional for the exchange-correlation energy in two dimensions

2010

We derive an approximate local density functional for the exchange-correlation energy to be used in density-functional calculations of two-dimensional systems. In the derivation we employ the Colle-Salvetti wave function within the scheme of Salvetti and Montagnani [Phys. Rev. A 63, 052109 (2001)] to satisfy the sum rule for the exchange-correlation hole. We apply the functional for the two-dimensional homogeneous electron gas as well as to a set of quantum dots and find a very good agreement with exact reference data.
