Conductivity magnetooscillations in 2D electron-impurity system under microwave irradiation: role of magnetoplasmons
E. E. Takhtamirov, V. A. Volkov
It is developed a many-electron approach to explain the recently observed conductivity magnetooscillations in very high mobility 2D electron systems under microwave irradiation. Fo…
Excited two-dimensional magnetopolaron states in quantum well of resonant tunnel junction
D. Yu. Ivanov, M. V. Chukalina, E. G. Takhtamirov +8
Tunnel spectroscopy is used to probe the electronic structure in GaAs quantum well of resonant tunnel junction over wide range of energies and magnetic fields normal to layers. Spi…
Development of the tunnelling gap in disordered 2D electron system with magnetic field: observation of the soft-hard gap transition
Yu. V. Dubrovskii, V. A. Volkov, L. Eaves +5
Magnetic field suppression of the tunneling between disordered 2D electron systems in GaAs around zero bias voltage has been studied. Magnetic field B normal to the layers induces…
Method of envelope functions and intervalley Γ-X_z interaction of states in (001) III-V semiconductor heterostructures
E. E. Takhtamirov, V. A. Volkov
The kp method is used to analyze the problem of intervalley Γ-X_z interaction of conduction band states in the (001) lattice-matched III-V semiconductor heterostructures. A conveni…
Generalization of the effective mass method for semiconductor structures with atomically sharp heterojunctions
E. E. Takhtamirov, V. A. Volkov
The Kohn-Luttinger envelope-function method is generalized to the case of heterostructures with atomically sharp heterojunctions based on lattice-matched layers of related semicond…
Orientational pinning of quantum Hall striped phase
E. E. Takhtamirov, V. A. Volkov
In ultra-clean 2D electron systems on (001) GaAs/AlGaAs upon filling high Landau levels, it was recently observed a new class of collective states, which can be related to the spon…
