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…
Shape-induced magnetic anisotropy in dilute magnetic alloys
V. N. Gladilin, V. M. Fomin, J. T. Devreese
We extend the theory of the surface-induced magnetic anisotropy to mesoscopic samples with arbitrary geometry. The shape-induced anisotropy of impurity spins in small brick-shaped…
Many-polaron system confined to a quantum dot: ground-state energy and optical absorption
J. T. Devreese, S. N. Klimin, V. M. Fomin +1
We find for the first time the ground state energy and the optical absorption spectra for N electrons (holes) interacting with each other and with the longitudinal optical (LO) pho…
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…
