Perfect absorption by metal-contacted two-dimensional systems with ultra-proximate reflectors
Kirill Kapralov, Vladislav Atlasov, Alina Khisameeva +2
Electromagnetic absorbance by most two-dimensional electron systems is typically well below unity, which hinders both practical applications in photodetection and fundamental studi…
Photocurrent at oblique illumination and reconstruction of wavefront direction with 2d photodetectors
Kirill Kapralov, Vladislav Atlasov, Alina Khisameeva +3
Many contemporary photodetectors operate beyond the readout of light intensity and enable the reconstruction of spectrum and polarization at the single-pixel level. However, the de…
Discovery of Slot Plasma Excitations in a AlGaN/GaN Plasmonic Crystal
A. R. Khisameeva, A. Shuvaev, I. M. Moiseenko +6
We experimentally investigate the terahertz spectrum of plasma excitations in a plasmonic crystal based on AlGaN/GaN two-dimensional electron system (2DES). While screened plasmon…
On the Nature of the Fundamental Plasma Excitation in a Plasmonic Crystal
A. R. Khisameeva, A. Shuvaev, A. A. Zabolotnykh +5
We report on the experimental study of the spectrum of plasma excitations in a plasmonic crystal fabricated from the two-dimensional electron system in an AlGaAs/GaAs semiconductor…
Piezoplasmonics: strain-induced tunability of plasmon resonance in AlAs quantum wells
A. R. Khisameeva, V. M. Muravev, I. V. Kukushkin
We demonstrate tuning of two-dimensional (2D) plasmon spectrum in modulation-doped AlAs quantum wells via the application of in-plane uniaxial strain. We show that dramatic change…
Achieving Balance of Valley Occupancy in Narrow AlAs Quantum Wells
A. R. Khisameeva, A. V. Shchepetilnikov, V. M. Muravev +7
Terahertz photoconductivity of m and m Hall bars fabricated from narrow AlAs quantum wells (QWs) of different widths is investigated in this paper. The photoresponse i…
Direct observation of energy spectrum transition in narrow AlAs quantum wells
A. R. Khisameeva, A. V. Shchepetilnikov, V. M. Muravev +8
Spectra of magnetoplasma excitations have been investigated in a two-dimensional electron systems in AlAs quantum wells (QWs) of different widths. The magnetoplasma spectrum have b…
Magnetoplasma excitations of two-dimensional anisotropic heavy fermions in AlAs quantum wells
V. M. Muravev, A. R. Khisameeva, V. N. Belyanin +5
The spectra of plasma and magnetoplasma excitations in a two-dimensional system of anisotropic heavy fermions were investigated for the first time. The spectrum of microwave absorp…
