Ground state energy of excitons in quantum dot treated variationally via Hylleraas-like wavefunction
(IOP PUBLISHING LTD, 2009)
In this work, the effects of quantum confinement on the ground state energy of a correlated electron-hole pair in a spherical and in a disc-like quantum dot have been investigated as a function of quantum dot size. Under ...
FINITE ELEMENT ANALYSIS OF VALENCE BAND STRUCTURE OF SQUARE QUANTUM WELL UNDER THE ELECTRIC FIELD
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Valence band structure with spin-orbit (SO) coupling of GaAs/Ga1-xAlxAs square quantum well (SQW) under the electric field by a calculation procedure based on a finite element method (FEM) is investigated using the multiband ...
Fourier transform technique in variational treatment of two-electron parabolic quantum dot
(IOP PUBLISHING LTD, 2009)
In this work, we propose an efficient method of reducing the computational effort of variational calculation with a Hylleraas-like trial wavefunction. The method consists of introducing integra transforms for the terms as ...
