Where are the edge-states near the quantum point contacts? A self-consistent approach

A. Siddiki, E. Cicek, D. Eksi +3

In this work, we calculate the current distribution, in the close vicinity of the quantum point contacts (QPCs), taking into account the Coulomb interaction. In the first step, we…

Theoretical investigation of the electron velocity in quantum Hall bars, in the out of linear response regime

A. Siddiki, D. Eksi, E. Cicek +3

We report on our theoretical investigation of the electron velocity in (narrow) quantum-Hall systems, considering the out-of-linear-response regime. The electrostatic properties of…

Local current distribution at large quantum dots (QDs): a self-consistent screening model

P. M. Krishna, A. Siddiki, K. Guven +1

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 distri…

The self-consistent calculation of the edge states at quantum Hall effect (QHE) based Mach-Zehnder interferometers (MZI)

A. Siddiki, A. E. Kavruk, T. Ozturk +2

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 i…

The spin-split incompressible edge states within empirical Hartree approximation at intermediately large Hall samples

Afif Siddiki

A self-consistent Thomas-Fermi-Poisson based calculation scheme is used to achieve spin resolved incompressible strips (ISs). The effect of exchange and correlation is incorporated…

Investigations on unconventional aspects in the quantum Hall regime of narrow gate defined channels

J. Horas, A. Siddiki, J. Moser +2

We report on theoretical and experimental investigations of the integer quantized Hall effect in narrow channels at various mobilities. The Hall bars are defined electrostatically…
