Tight-binding calculations of image charge effects in colloidal nanoscale platelets of CdSe
R. Benchamekh, N. A. Gippius, J. Even +6
CdSe nanoplatelets show perfectly quantized thicknesses of few monolayers. They present a situation of extreme, yet well defined quantum confinement. Due to large dielectric contra…
Excitonic parameters of GaN studied by time-of-flight spectroscopy
T. V. Shubina, A. A. Toropov, G. Pozina +7
We refine excitonic parameters of bulk GaN by means of time-of-flight spectroscopy of light pulses propagating through crystals. The influence of elastic photon scattering is exclu…
Coherent interactions between phonons and exciton or exciton-polariton condensates
D. V. Vishnevsky, N. A. Gippius, I. A. Shelykh +2
We analyse the interaction of exciton and exciton-polariton condensates in semiconductor microcavity with a coherent acoustic wave. An analytical solution for the dispersion of exc…
Delay and distortion of slow light pulses by excitons in ZnO
T. V. Shubina, M. M. Glazov, N. A. Gippius +8
Light pulses propagating through ZnO undergo distortions caused by both bound and free excitons. Numerous lines of bound excitons dissect the pulse and induce slowing of light arou…
Terahertz radiation due to random grating coupled surface plasmon polaritons
T. V. Shubina, N. A. Gippius, V. A. Shalygin +2
We report on terahertz (THz) radiation under electrical pumping from a degenerate semiconductor possessing an electron accumulation layer. In InN, the random grating formed by topo…
InN/In nanocomposites: Evidences of plasmonic effects and hidden gap
T. V. Shubina, V. A. Kosobukin, T. A. Komissarova +9
InN/In nanocomposites with periodical In inclusions amounting up to 30% of the total volume exhibit bright emission near 0.7 eV explicitly associated with In clusters. Its energy a…

Resonant light delay in GaN with ballistic and diffusive propagation
T. V. Shubina, M. M. Glazov, A. A. Toropov +8
We report on a strong delay in light propagation through bulk GaN, detected by time-of-flight spectroscopy. The delay increases resonantly as the photon energy approaches the energ…
