Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ...
Current-direction-induced rectification effect on (integer) quantized Hall plateaus
(Edp Sciences S A, 2009)
Current distribution across narrow Hall bars in out of linear response regime is studied within a self-consistent Hartree-type mean-field approximation for samples which are equally and unequally depleted laterally. The ...
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 ...
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 ...
Comparative effects of various salicylic acid derivatives on key growth parameters and some enzyme activities in salinity stressed maize (Zea mays L.) plants
(Pakistan Botanical Soc, 2007)
Salicylic acid, 5-Sulfo Salicylic acid and Acetylsalicylic acid are Salicylic acid derivatives. They differ in their substitution on the benzene ring and m ay have different effects on plant 0 in membranes, The effects of ...
Design and construction of uniform glow discharge plasma system operating under atmospheric condition
(Amer Inst Physics, 2007)
The design of a uniform glow discharge plasma system operating without vacuum is presented. A full-bridge switching circuit was used to switch the transformers. The primary windings of transformers were connected in parallel, ...
The genetic basis of malathion resistance in housefly (Musca domestica L.) strains from Turkey
(Springer, 2004)
Organophosphate insecticide (parathion/diazinon) resistance in housefly ( Musca domestica L.) is associated with the change in carboxylesterase activity. The product of MdalphaE7 gene is probably playing a role in ...
Staple holding strength of furniture frame joints constructed of plywood and oriented strandboard
(Forest Products Soc, 2003)
Staples are common in the construction of upholstered furniture. Staples are most common for the attachment of fabric to the frame, but they are also now being used in the construction of the frame itself because they ...
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION
(Estonian Academy Publishers, 2009)
The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were ...
