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…
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…
