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 ...
Spatial distribution of the incompressible strips at AB interferometer
(Elsevier Science Bv, 2010)
In this work, the edge physics of an Aharonov-Bohm interferometer (ABI) defined on a two dimensional electron gas, subject to strong perpendicular magnetic field B, is investigated. We solve the three dimensional Poisson ...
The current polarization rectification of the integer quantized Hall effect
(Elsevier Science Bv, 2010)
We report on our theoretical investigation considering the widths of quantized Hall plateaus (QHPs) depending on the density asymmetry induced by the large current within the out-of-linear response regime. We solve the ...
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 ...
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 effect of aging on the dark conductivity and noise in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Aging hydrogenated microcrystalline silicon in air is found to affect both the dark conductivity and the 1/f noise. For a sample with a crystalline volume fraction of 0.39, the conductivity decreased by three orders of ...
Investigation of light induced degradation in hydrogenated amorphous silicon-germanium alloy thin films using temperature dependent photoconductivity
(Wiley-V C H Verlag Gmbh, 2010)
Light induced degradation of undoped hydrogenated amorphous silicon-germanium (a-SiGe:H) alloys with different Ge contents has been investigated using intensity and temperature dependence of photoconductivity between 78K ...
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 ...
