Lamb Shift of Landau Levels in Two-Dimensional Electron Systems in a Multimode Resonator
Aleksandr Shabanov, Georgy Alymov, Dmitry Svintsov
The use of resonators to modify the behavior of electromagnetic systems demonstrates its potential for application in a wide range of problems. However, existing theoretical studie…
Physical quantities as a partially additive field
Georgy Alymov
We generalize the concept of a field by allowing addition to be a partial operation. We show that elements of such a "partially additive field" share many similarities with physica…
Ultimate sharpness of the tunneling resonance in vertical heterostructures
Georgy Alymov, Dmitry Svintsov
Heterostructures comprised of two two-dimensional electron systems (2DES) separated by a dielectric exhibit resonant tunneling when the band structures of both systems are aligned.…
Refraction laws for two-dimensional plasmons
Dmitry Svintsov, Georgy Alymov
Despite numerous applications of two-dimensional plasmons for electromagnetic energy manipulation at the nanoscale, their quantitative refraction and reflection laws (analogs of Fr…
Ultralow-noise terahertz detection by p-n junctions in gapped bilayer graphene
Elena Titova, Dmitry Mylnikov, Mikhail Kashchenko +6
Graphene shows a strong promise for detection of terahertz (THz) radiation due to its high carrier mobility, compatibility with on-chip waveguides and transistors, and small heat c…
One-dimensional electron localization in semiconductors coupled to electromagnetic cavities
Dmitry Svintsov, Georgy Alymov, Zhanna Devizorova +1
Electrical conductivity of one-dimensional (1d) disordered solids decays exponentially with their length, which is a celebrated manifestation of the localization phenomenon. Here,…
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…
Feasibility of lasing in the GaAs Reststrahlen band with HgTe multiple quantum well laser diodes
Aleksandr Afonenko, Dmitry Ushakov, Georgy Alymov +4
Operation of semiconductor lasers in the 20--50 m wavelength range is hindered by strong non-radiative recombination in the interband laser diodes, and strong lattice absorption…
Tunnel field-effect transistors for sensitive terahertz detection
Igor Gayduchenko, Shuigang Xu, Georgy Alymov +9
The rectification of electromagnetic waves to direct currents is a crucial process for energy harvesting, beyond-5G wireless communications, ultra-fast science, and observational a…
Fundamental limits to far-infrared lasing in Auger-suppressed HgCdTe quantum wells
Georgy Alymov, Vladimir Rumyantsev, Sergey Morozov +3
A challenge of bridging the terahertz gap with semiconductor lasers faces an inevitable problem of enhanced non-radiative Auger recombination with reduction of photon energy. We sh…
Auger recombination in Dirac materials: A tangle of many-body effects
Georgy Alymov, Vladimir Vyurkov, Victor Ryzhii +2
The peculiar electron dispersion in Dirac materials makes lowest-order Auger processes prohibited or marginally prohibited by energy and momentum conservation laws. Thus, Auger rec…
Abrupt current switching in graphene bilayer tunnel transistors enabled by van Hove singularities
G. Alymov, V. Vyurkov, V. Ryzhii +1
In a continuous search for the energy-efficient electronic switches, a great attention is focused on tunnel field-effect transistors (TFETs) demonstrating an abrupt dependence of t…
