Journal ArticleDOI
Vibrational and Electronic Structure of Hydrogen-Related Defects in Silicon Calculated by the Extended Hückel Theory
TL;DR: Extended Huckel theory calculations are carried out for interstitial hydrogen atoms in silicon model crystals without and with vacancies as discussed by the authors, and the vibrational frequencies for all defect types considered are in very close agreement with infrared bands observed after proton irradiation of silicon.
Journal ArticleDOI
Porous silicon: theoretical studies
George C. John,Vijay A. Singh +1 more
TL;DR: A review of the theoretical work done on this material can be found in this article, where the authors describe the classical theories and computer simulations of the growth of this brittle, spongy structure.
Journal ArticleDOI
Theory of the photoluminescence spectra of porous silicon.

Journal ArticleDOI
Path integrals with a periodic constraint: Entangled strings
Akira Inomata,Vijay A. Singh +1 more
TL;DR: In this paper, the path integral for a string entangled around a singular point in two dimensions is evaluated in polar coordinates and applications are made for the entangled polymers with and without interactions, the Aharonov-Bohm effect and the angular momentum projection of a spinning top.
Journal ArticleDOI
Shallow-deep transitions of impurities in semiconductor nanostructures
Vivek Ranjan,Vijay A. Singh +1 more
TL;DR: In this article, the authors employ the effective mass theory with realistic barrier and variable effective mass to study the hydrogenic impurity in a quantum dot (QD) and show that the depth of the HO becomes shallow and at times resonant with the conduction band.
