Magnetotransport in a pseudomorphic GaAs/Ga0.8In0.2As/Ga0.75Al0.25As heterostructure with a Si delta -doping layer.
Magnetotransport properties of a pseudomorphic GaAs/ Ga0.8In0.2As/Ga0.75Al0.25As heterostructure are investigated in pulsed magnetic fields up to 50 T and at temperatures of T =1.4 K and 4.2 K. The structure studied consists of a Si δ-layer parallel to a Ga0.8In0.2As quantum well (QW). The dark electron density of the structure is ne = 1.67×1016 m−2. By illumination the density can be increased...
متن کاملEffect of Welding Heat Input on the Intermetallic Compound Layer and Mechanical Properties in Arc Welding-brazing Dissimilar Joining of Aluminum Alloy to Galvanized Steel
The effect of weld heat input on the formation of intermetallic compound (IMCs) layer during arc welding–brazing of aluminium and steel dissimilar alloys, was investigated through both finite element method (FEM) numerical simulations and experimental measurements. The results of FEM analysis as well as welding experiments indicated that increasing weld heat input increases the thickness of IMC...
متن کاملMagnetoresistance and charge transport in graphene governed by nitrogen dopants.
We identify the influence of nitrogen-doping on charge- and magnetotransport of single layer graphene by comparing doped and undoped samples. Both sample types are grown by chemical vapor deposition (CVD) and transferred in an identical process onto Si/SiO2 wafers. We characterize the samples by Raman spectroscopy as well as by variable temperature magnetotransport measurements. Over the entire...
متن کاملEffects of Various Ageing Heat Treatments on Microstructural Features and Hardness of Piston Aluminum Alloy
Piston aluminum alloys have different intermetallic phases, such as Cu3Al, Mg2Si ,and AlNi phases. The morphology and the distribution of such phases have important roles on mechanical properties of the piston material. Therefore, in this research, various ageing heat treatments on the mentioned material were done and the microstructural feature and the hardness were studi...
متن کاملHOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...
