Direct bandgap optical transitions in Si nanocrystals
A. A. Prokofiev, A. S. Moskalenko, I. N. Yassievich +5
The effect of quantum confinement on the direct bandgap of spherical Si nanocrystals has been modelled theoretically. We conclude that the energy of the direct bandgap at the -p…

Carrier relaxation in Si/SiO quantum dots
A. A. Prokofiev, S. V. Goupalov, A. S. Moskalenko +2
Carrier relaxation due to both optical and nonradiative intraband transitions in silicon quantum dots in SiO has been considered. Interaction of confined holes with optical pho…

Magnetic field effect on tunnel ionization of deep impurities by terahertz radiation
S. D. Ganichev, S. N. Danilov, M. Sollinger +6
A suppression of tunnelling ionization of deep impurities in terahertz frequency electric fields by a magnetic field is observed. It is shown that the ionization probability at ext…
