Multivalued dispersion equation for plasmon-surface optical phonon coupling in graphene/polar substrate system
S. M. Kukhtaruk, V. A. Kochelap
Dispersion equations are a common paradigm of collective excitation physics. However, in some systems, dispersion equations contain multivalued functions and their solutions are am…
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…
Semiclassical analysis of intraband collective excitations in a two-dimensional electron gas with Dirac spectrum
S. M. Kukhtaruk, V. A. Kochelap
Solving the initial value problem for semiclassical equations that describe two-dimensional electrons with the Dirac spectrum we found that collective excitations of the electrons…
Wave excitations of drifting two-dimensional electron gas under strong inelastic scattering
V. V. Korotyeyev, V. A. Kochelap, L. Varani
We have analyzed low-temperature behavior of two-dimensional electron gas in polar heterostructures subjected to a high electric field. When the optical phonon emission is the fast…
Interaction between an Isotropic Nanoparticle and Drifting Electrons in a Quantum Well
V. A. Kochelap, S. M. Kukhtaruk
A hybrid system composed of an isotropic nanoparticle and a semiconductor heterostructure with a quantum well has been considered. The nanoparticle is supposed to be polarizable in…
Voltage controlled terahertz transmission through GaN quantum wells
T. Laurent, R. Sharma, J. Torres +13
We report measurements of radiation transmission in the 0.220--0.325 THz frequency domain through GaN quantum wells grown on sapphire substrates at room and low temperatures. A sig…
