Changes in the magnetic behavior of melt-textured Sm1.6Ba2.3Cu3.O-3(x) superconductor due to thermal neutron irradiation were investigated at 50 and 77 K. It was observed that J(c) was enhanced up to five times in magnitude after a irradiation fluency of 1.476 x 10(17) cm(-2). We discuss which types of pinning centers can be responsible for the observed behavior.


Effect of B2O3 addition on the formation and properties of Tl-2212 and Tl-2223 superconductors
Cavdar, S; Aksu, E; Koralay, H; Ozkan, H; Hasanlı, Nızamı; Ercan, I (Wiley, 2003-09-01)
We have studied the effect of B2O3 addition on the formation and properties of the Tl-based superconductors. Polycrystalline Tl-2212 and Tl-2223 samples were synthesized by adding B2O3 to the chemicals at the first and at the second stage of two stages sintering processes (3+1 h) at 860 C. X-ray powder diffraction patterns, resistance versus temperature behaviours and the micrographs of the B2O3 free and B2O3 added samples have been analysed. The compositions and the critical temperatures of the samples ind...
Effect of calcium or yttrium doping on cation ordering and electrochemical performance of Li(Ni0.80-xCo0.15Al0.05Mx)O-2 (M = Ca, Y) as a Li-ion battery cathode

The electrochemical performance of Li(Ni-0.80-xCo(0.15)Al(0.05)M(x))O-2 (NCA) cathode was demonstrated to be improved by calcium and yttrium doping. Samples were synthesized by ultrasonic sound-assisted co-precipitation method which satisfied precipitation of nano-sized particles around 20 nm. Doping elements were introduced to the structure by solid-state reaction route and single phase, layered Li-0.993(Ni0.804Co0.154Al0.035Y0.014)O-2 +/-sigma and Li-0.991(Ni0.801Co0.152Al0.037Y0.019)O-2 +/-sigma samples ...

Ogun, SE; Ozkan, H; Hasanlı, Nızamı (Institute of Electrical and Electronics Engineers (IEEE), 2003-06-01)
The effect of Li addition on the formation and properties of Pb containing Bi-based superconductors has been studied. Three successive thermal sintering cycles have been applied to the oxides adjusted for the nominal composition, Bi1.6Pb0.4Sr2CaCu2O8+d. Eight different samples having Li2CO3 from 0.0 up to 3.0 weight% have been synthesized, X-ray diffraction patterns, resistivity-temperature behaviors and differential thermal analysis of the samples have been examined. Li2CO3 addition at 650degreesC decrease...
Effects of screening on the two-dimensional electron transport properties in modulation doped heterostructures
Sen, O; Beşikci, Cengiz; Tanatar, B (Elsevier BV, 1998-06-01)
The effects of screening on the polar optical phonon scattering rates and on the transport properties of the two-dimensional electron gas in AlGaAs/GaAs modulation doped heterostructures have been investigated through Monte Carlo simulations incorporating the three valleys of the conduction band, size quantization in the Gamma valley and the lowest three subbands in the quantum-well. At typical sheet densities observed in modulation doped field-effect transistors, screening considerably affects the electron...

The influence is investigated of silicon wafer treatment in the alkali etchant with surface orientation close to planes (111), (100), and (110) on the magnitude of mechanical strength, It is shown that the dependence of the mechanical strength of silicon wafers on the etch time in the alkali etchant irrespective of orientation planes has a complex characteristics, namely: with the increase of etch time the mechanical strength increases, reaches its maximum value and with the further etch time growth it decr...
