Gurzhi, R. N., Kalinenko, A. N., Kopeliovich, A. I., Yanovsky, A. V., Bogachek, E. N., Landman, Uzi
A method for the evaluation of the angular width of an electron beam generated by a nanoconstriction is proposed and demonstrated. The approach is based on analysis of a narrow-width electron flow,...
A Magnetic-Field-Effect Transistor and Spin Transport (2003)
Gurzhi, R. N., Kalinenko, A. N., Kopeliovich, A. I., Yanovsky, A. V., Bogachek, E. N., Landman, Uzi
A magnetic-field-effect transistor is proposed that generates a spin-polarized current and exhibits a giant negative magnetoresitance. The device consists of a nonmagnetic conducting channel (wire or...
Gurzhi, R. N., Kopeliovich, A. I., Kalinenko, A. N., Yanovsky, A. V., Bogachek, E. N., Landman, Uzi, ...
A theory is developed for the evolution of the non-equilibrium distribution of quasiparticles when the scattering rate decreases due to particle collisions. We propose a "modified one-collision...
Spin-Guide: A New Source of High Spin-Polarized Current (2003)
Gurzhi, R. N., Kalinenko, A. N., Kopeliovich, A. I., Yanovsky, A. V., Bogachek, E. N., Landman, Uzi
We propose a ``spin-guide'' source for generation of electric currents with a high degree of spin polarization, allowing long-distance transmission of the spin-polarization. In the spin-guide scheme...
Non-Magnetic Spinguides and Spin Transport in Semiconductors (2001)
Gurzhi, R. N., Kalinenko, A. N., Kopeliovich, A. I., Yanovsky, A. V.
We propose the idea of a "spinguide", i.e. the semiconductor channel which is surrounded with walls from the diluted magnetic semiconductor (DMS) with the giant Zeeman splitting which are transparent...
Angle-Resolved Spectroscopy of Electron-Electron Scattering in a 2D System (2000)
Yanovsky, A. V., Predel, H., Buhmann, H., Gurzhi, R. N., Kalinenko, A. N., Kopeliovich, A. I., ...
Electron-beam propagation experiments have been used to determine the energy and angle dependence of electron-electron (ee) scattering a two-dimensional electron gas (2DEG) in a very direct manner by...
Predel, H., Buhmann, H., Molenkamp, L. W., Gurzhi, R. N., Kalinenko, A. N., Kopeliovich, A. I., ...
We have studied experimentally and theoretically the influence of electron-electron collisions on the propagation of electron beams in a two-dimensional electron gas for excess injection energies...
