Temperature dependent behavior of localized and delocalized electrons in nitrogen-doped 6H SiC crystals as studied by electron spin resonance
D. Savchenko, E. Kalabukhova, B. Shanina +4
We have studied the temperature behavior of the electron spin resonance (ESR) spectra of nitrogen (N) donors in n-type 6H SiC crystals grown by Lely and sublimation sandwich method…
Spatially dispersive dynamical response of hot carriers in doped graphene
S. M. Kukhtaruk, V. A. Kochelap, V. N. Sokolov +1
We study theoretically wave-vector and frequency dispersion of the complex dynamic conductivity tensor (DCT), , of doped monolayer graphene under a strong dc…
Microwave-induced magnetooscillations and signatures of zero-resistance states in phonon-drag voltage in two-dimensional electron systems
A. D. Levin, Z. S. Momtaz, G. M. Gusev +2
We observe the phonon-drag voltage oscillations correlating with the resistance oscillations under microwave irradiation in a two-dimensional electron gas in perpendicular magnetic…
Modeling of the substrate influence on multielement THz detector operation
M. Sakhno, J. Gumenjuk-Sichevska, F. Sizov
The development of THz multielement uncooled imagers based on focal plane arrays (FPAs) requires an optimization of the system parameters to achieve a homogeneous sensitivity of th…
Modeling of electron energy spectra and mobilities in semi-metallic Hg1-xCdxTe quantum wells
E. O. Melezhik, J. V. Gumenjuk-Sichevska, F. F. Sizov
Electron mobility, energy spectra and intrinsic carrier concentrations in the n-type Hg0.32Cd0.68Te / Hg1-xCdxTe / Hg0.32Cd0.68Te quantum well (QW) in semi-metallic state are numer…
THz lattice vibrations for active plasmonics with light: Ultrafast optical response in gold/telluride hybrid plasmonic crystals
Lars E. Kreilkamp, Ilya A. Akimov, Vladimir I. Belotelov +10
Excitation of coherent optical phonons in solids provides a pathway for ultrafast modulation of light on a sub-ps timescale. Here, we report on efficient 3.6 THz modulation of ligh…
