Influence of a Temperatures on the Quantum Hall Effect in Cylindrical Quantum Wires with Asymmetrical Parabolic Potential
Downloads
The Hall effect is studied theoretically in a Cylindrical Quantum Wire (CQW) with asymmetrical parabolic potential to a dc electric field , a magnetic field and a laser radiation (where and are the amplitude and the frequency of the laser radiation, respectively). By using the quantum kinetic equation method for electrons interacting with Acoustic Phonon (AP), we obtain analytical expressions for the conductivity tensor and the Hall Coefficient (HC). Numerical calculations are also applied for GaAs/GaAsAl CQW to show the nonlinear dependence of the HC on the temperatures of system.
