Competition between isotropic and strongly anisotropic terms in the impact ionization rate of narrow- and middle-gap cubic semiconductors
A. N. Afanasiev, A. A. Greshnov, G. G. Zegrya
We report on the strong anisotropy of the inter-band process of impact ionization in direct-gap cubic semiconductors with either weak or strong spin-orbit coupling at low effective…
Size Effect in Electron Paramagnetic Resonance Spectra of Impurity Centers in Diamond Nanoparticles
G. G. Zegrya, D. M. Samosvat, V. Yu. Osipov +2
The evolution of the polycrystalline pattern of electron paramagnetic resonance (EPR) spectra of intrinsic and induced paramagnetic centers in an ensemble of submicrometer diamond…
Resonance electronic excitation energy transfer in the quantum dot system
O. P. Chikalova-Luzina, D. M. Samosvat, V. M. Vyatkin +1
Microscopic theory of the nonradiative energy transfer in a system of III-V semiconductor quantum dots is elaborated in our work. The energy transfer both due to direct Coulomb and…
On the impact ionization rate in direct gap semiconductors
A. N. Afanasiev, A. A. Greshnov, G . G. Zegrya
We present quantum-mechanical theory of impact ionization in semiconductors with the direct band gap in $Γ$-point. It is shown that energy dependence of the impact ionization rat…
Precision of Quantization of the Hall Conductivity in a Sample of Finite Size: Power Law
A. A. Greshnov, G. G. Zegrya, E. N. Kolesnikova
A microscopic calculation of the conductivity in the integer quantum Hall effect (IQHE) regime is carried out. The problem of precision of quantization is analyzed for samples of f…
Electron-Electron Relaxation Effect on Auger Recombination in Direct Band Semiconductors
Anatoli Polkovnikov, Georgy Zegrya
Influence of electron-electron relaxation processes on Auger recombination rate in direct band semiconductors is investigated. Comparison between carrier-carrier and carrier-phonon…
