Analytic calculation of ground state properties of the 2d and 3d electron gas
(Bilkent University, 2015-06)The electron gas (2D and 3D) is a model which consists of interacting electrons moving in a uniform positive background. Its importance stems from the fact that a number of metals behave similarly, it provides the ... -
Complementary and alternative technique for the determination of electron effective mass: Quantum hall effect
(Taylor & Francis Inc., 2016)The quantum Hall effect measurements in the AlInN/AlN/GaN heterostructure are studied in the temperature range from 1.8 K to 14 K and a magnetic field up to 11 T. The quantized two-dimensional electron gas was placed at ... -
Landau levels in lattices with long - range hopping
(American Physical Society, 2013)Landau levels (LLs) are broadened in the presence of a periodic potential, forming a barrier for accurate simulation of the fractional quantum Hall effect using cold atoms in optical lattices. Recently, it has been shown ... -
Local current distribution at large quantum dots (QDs): A self-consistent screening model
(Elsevier B.V., 2008)We report the implementation of the self-consistent Thomas-Fermi screening theory, together with the local Ohm's law to a quantum dot system in order to obtain local current distribution within the dot and at the leads. ... -
The self-consistent calculation of the edge states at quantum Hall effect (QHE) based Mach-Zehnder interferometers (MZI)
(Elsevier B.V., 2008)The spatial distribution of the incompressible edge states (IES) is obtained for a geometry which is topologically equivalent to an electronic Mach-Zehnder interferometer, taking into account the electron-electron interactions ... -
A self-consistent microscopic model of Coulomb interaction in a bilayer system as an origin of Drag Effect Phenomenon
(Elsevier B.V., 2008)In this work we implement the self-consistent Thomas-Fermi model that also incorporates a local conductivity model to an electron-electron bilayer system, in order to describe novel magneto-transport properties such as the ...
