Photoluminescence of tetrahedral quantum-dot quantum wells
V. A. Fonoberov, E. P. Pokatilov, V. M. Fomin +1
Taking into account the tetrahedral shape of a quantum dot quantum well (QDQW) when describing excitonic states, phonon modes and the exciton-phonon interaction in the structure, w…

Optical spectra of quantum dots: effects of non-adiabaticity
J. T. Devreese, V. M. Fomin, E. P. Pokatilov +2
It is shown that in many cases an adequate description of optical spectra of semiconductor quantum dots requires a treatment beyond the commonly used adiabatic approximation. We ha…
Reply to the comment by E. Menendez-Proupin on "Multi-phonon Raman scattering in semiconductor nanocrystals: Importance of non-adiabatic transitions"
E. P. Pokatilov, S. N. Klimin, V. M. Fomin +2
In our recent paper [Phys. Rev. B 65, 075316 (2002)], the selection rules for the Raman scattering in spherical nanocrystals are analyzed. Here we show, that a physically expedient…
Quantum transport in the cylindrical nanosize silicon-based MOSFET
S. N. Balaban, E. P. Pokatilov, V. M. Fomin +6
A model is developed for a detailed investigation of the current flowing through a cylindrical nanosize MOSFET with a close gate electrode. The quantum mechanical features of the l…
