Bandgaps and band bowing in semiconductor alloys
Titus Sandu, Radu I. Iftimie
The bandgap and band bowing parameter of semiconductor alloys are calculated with a fast and realistic approach. The method is a dielectric scaling approximation that is based on a…
Real space screened-exchange method for semiconductors and their alloys
Titus Sandu, R. I. Iftimie, M. van Schilfgaarde
This paper has been withdrawn by the author(s), due a crucial error in Eqn. 30.
Spin tunneling through an indirect barrier
Titus Sandu, Athanasios Chantis, Radu Iftimie
Spin-dependent tunneling through an indirect bandgap barrier like the GaAs/AlAs/GaAs heterostructure along [001] direction is studied by the tight-binding method. The tunneling is…
An efficient Monte Carlo method for calculating ab initio transition state theory reaction rates in solution
Radu Iftimie, Dennis Salahub, Jeremy Schofield
In this article, we propose an efficient method for sampling the relevant state space in condensed phase reactions. In the present method, the reaction is described by solving the…
