Screening theory based modeling of the quantum Hall based quasi-particle interferometers, defined at quantum dots
(Elsevier Science Bv, 2012)
In this work, we investigate the spatial distributions and the widths of the incompressible strips, i.e. the edge-states. The incompressible strips that correspond to nu = 1,2 and 1/3 filling factors are examined in the ...
Stability of spin droplets in realistic quantum Hall devices
(Iop Publishing Ltd, 2013)
We study the formation and characteristics of 'spin droplets', i.e. compact spin-polarized configurations in the highest occupied Landau level, in an etched quantum Hall device at filling factors 2 <= nu <= 3. The confining ...
Interaction-mediated asymmetries of the quantized Hall effect
(Epl Association, European Physical Society, 2009)
Experimental and theoretical investigations on the integer quantized Hall effect in gate-defined narrow Hall bars are presented. At low electron mobility the classical (high-temperature) Hall resistance line R(H)(B) cuts ...
The visibility of IQHE at sharp edges: experimental proposals based on interactions and edge electrostatics
(Iop Publishing Ltd, 2012)
The influence of the incompressible strips on the integer quantized Hall effect (IQHE) is investigated, considering a cleaved-edge overgrown (CEO) sample as an experimentally realizable sharp edge system. We propose a set ...
Electrostatic screening and experimental evidence of a topological phase transition in a bulk quantum Hall liquid
(Iop Publishing Ltd, 2009)
The electrostatic screening of a medium disordered quantum Hall liquid was investigated using an electric field penetration (EFP) technique. At sufficiently low temperatures and at magnetic fields corresponding to the ...
The effect of disorder on integer quantized Hall effect
(Elsevier, 2012)
We study the effects of disorder on the integer quantized Hall effect within the screening theory, systematically. The disorder potential is analyzed considering the range of the potential fluctuations. The short-range ...
Structural, Electrical, and Magnetic Properties of High-Temperature-Sintered La1-xNaxMnO3 (0.05 <= x <= 0.35) Compounds
(Springer, 2015)
The structural, electric, and magnetic properties of La1-xNaxMnO3 (0.05 <= x <= 0.35) compounds have been investigated. The compounds were prepared by a standard sol-gel method then sintered at 1400 degrees C for 24 h. The ...
Anchoring transitions in nematic-discotic lyotropic mesophase under magnetic field
(Natl Inst Optoelectronics, 2015)
Magneto-morphologic and orientational properties of the lyotropic nematic-discotic N-D mesophase have been studied by the polarizing optical microscopy technique. Texture transformations from the schlieren texture to the ...
The effects of native and light induced defects on optoelectronic properties of hydrogenated amorphous silicon-germanium (a-SiGe:H) alloy thin films
(Springer, 2010)
Effects of native and light induced defects states in hydrogenated amorphous silicon-germanium alloy thin films with different Ge concentrations have been investigated by using steady-state photoconductivity, dual beam ...
Investigation of meta- and in-stability effects in hydrogenated microcrystalline silicon thin films by the steady-state measurement methods
(Canadian Science Publishing, Nrc Research Press, 2014)
Metastability effects because of atmospheric exposure, high purity gasses, and deionized water in hydrogenated microcrystalline silicon thin films with different crystalline volume fractions were studied using well accepted ...
