Impact ionization in narrow band gap CdHgTe quantum well with "resonant" band structure
V. Ya. Aleshkin, A. A. Dubinov, V. V. Rumyantsev
Impact ionization probabilities were calculated in a CdHgTe quantum well, where the distance between electron subbands is close to the band gap energy. This band structure enables…
Stimulated emission of plasmon-LO mode in narrow gap HgTe/CdHgTe quantum wells
V. Ya. Aleshkin, A. A. Dubinov, V. I. Gavrilenko +1
We calculate the dispersion of the plasmon-LO modes taking into account the spatial dispersion of the electronic polarizability. It is shown that stimulated emission of the plasmon…
Plasmon recombination in narrowgap HgTe quantum wells
V Ya Aleshkin, G Alymov, A A Dubinov +2
The dispersion laws of two-dimensional plasmons in narrow-gap HgTe/CdHgTe quantum wells are calculated taking into account the spatial dispersion of the electron susceptibility. At…
Amplification of surface plasmons in graphene-black phosphorus injection laser heterostructures
V. Ryzhii, T. Otsuji, M. Ryzhii +4
We propose and evaluate the heterostructure based on the graphene-layer (GL) with the lateral electron injection from the side contacts and the hole vertical injection via the blac…
Interband infrared photodetectors based on HgTe--CdHgTe quantum-well heterostructure
V. Ya. Aleshkin, A. A. Dubinov, S. V. Morozov +5
We calculate the characteristics of interband HgTe-CdHgTe quantum-well infrared photodetectors (QWIPs). Due to a small probability of the electron capture into the QWs, the interba…
Ultra-compact injection terahertz laser using the resonant inter-layer radiative transitions in multi-graphene-layer structure
Alexander A. Dubinov, Andrey Bylinkin, Vladimir Ya. Aleshkin +3
The optimization of laser resonators represents a crucial issue for the design of terahertz semiconductor lasers with high gain and low absorption loss. In this paper, we put forwa…
