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 decreases and acquires values less than the ultimate strength. The analysis of the experimental results shows a close connection between the mechanical strength changes and the microstructure of the distorted layer of the silicon wafer surface.

EFFECT OF GAMMA-IRRADIATION AND SILVER DOPING ON YBCO SUPERCONDUCTOR
OZKAN, H; ALBISS, BA; HAMDAN, N; MENARD, A (Springer Science and Business Media LLC, 1994-12-01)
The effect of gamma-irradiation and silver doping on the properties of YBCO superconductors has been studied by electrical resistance measurements and x-ray diffraction techniques. The zero-resistance superconducting transition temperature of (YBCO)(1-x)Ag-x systematically increase by about 2 K with an increase of Ag content up to x = 0.04. Further increase in Ag content decreases the transition temperature. The normal-state resistance decreases up to a factor of 3.4 with an increase of Ag content. No signi...
THE EFFECT OF A 3RD COMPONENT IMPURITY-C ON THE HEAT-CAPACITY OF A3B-TYPE ORDERED ALLOYS
Mehrabov, Amdulla; MATYSINA, ZA (Wiley, 1989-12-01)
For the first time theoretical (in terms of the classical theory of ordering) and experimental (with the adiabatic calorimeter method) investigations are made of the effect of a third component impurity C on the heat capacity of A3B‐type ordered alloys with FCC structure. The effect of the impurities Mn, Cr, Mo, or W on the heat capacity of Ni3Fe alloys is analysed as an example. The comparison of the theoretical results with the experimental data shows good qualitative agreement.
ANOMALOUS AMPLITUDE DEPENDENT DISLOCATION DAMPING ASSOCIATED WITH ANHARMONIC OSCILLATIONS OF A COULOMBIC KINK CHAIN IN THE NONLINEAR DISSIPATIVE ATMOSPHERE OF IMPURITY ATOMS
OGURTANI, TO (Wiley, 1991-11-16)
The effects of the anharmonic interaction of the Coulombic kink chain on the strength and the position of the cold-work internal friction peaks associated with the nonlinearly power dissipating impurity atoms are investigated by a novel numerical simulation of the related discrete mathematical macro-model. The present macroscopic model of dislocation damping which relies heavily on the microscopic theory of kink-interstitial interactions shows very strong anomalous strain amplitude as well as the bias stres...
Effect of Li addition on the properties of Bi-based superconductors
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...
Characteristics of HfO2 and SiO2 on p-type silicon wafers using terahertz spectroscopy
Altan, Hakan; Pham, D.; Grebel, H.; Federici, J. F. (IOP Publishing, 2007-05-01)
The effect of high-kappa dielectric HfO2 films on 200 mm diameter p-type silicon substrates was investigated and compared with conventional dielectric material, SiO2. We employed all-optical characterization methods using terahertz (THz) time-domain spectroscopy and visible cw pump/THz probe spectroscopy. Measurements were performed on two sets of samples, each set containing both HfO2 and SiO2 coated wafers with varying thickness of oxide layer. One set had a protective coating of either photoresist or Si3...
