Distribution of Components in SiGe Bulk Crystals Grown by the Zone Levelling Method

A numerical model, using the equilibrium distribution coefficient defined in the phase diagram, capable of predicting the component redistribution in Si-Ge crystal at any stage of the zone leveling growth, is proposed. Compositional profiles of Si-Ge crystals with a variety of operational parameters, such as the molten zone length and the initial ingot composition, are calculated and discussed. It was found that the Si concentration profile in Si-Ge crystal as a function of zone length changes considerably from fully graded to almost uniform along the growth direction. Obtained results allow the operational parameters for preparing Si-Ge mixed crystal to be estimated. PACS. 61.72.Ss - Impurity concentration, distribution, an...

Calculation of diffusion coefficient in Au diffusion-doped Bi1.8Pb0.35Sr1.9Ca2.1Cu3Oy by EDXRF measurements

It is found that the Au diffusion coefficient decreases as the diffusion-annealing temperature decreases. The temperature dependences of Au diffusion coefficient in grains and over grain boundaries are described by the relations D1=6.7 x 10-5exp(-1.19eV/kBT) and D2=9.7 x 10-4exp(-1.09eV/kBT), respectively. The diffusion doping of Bi-2223 by Au causes a significant increase of the lattice parameter c by about 0.19%. For the Au-diffused samples, transport measurements indicated the Tc increased from 100 to 104K and the Jc increased from 40 to 125Acm-2, in comparison with those of undoped samples. From SEM and XRD measurements it is observed that Au doping of the sample also improved the surface morphology and increased the ratio of the high-Tc phase to the low-Tc phase. The possible reasons for the observed improvement due to Au diffusion are ...

Hatta turizm projeleri, ticaret ve sanayi girişimlerine engel olmak şöyle dursun, diğer sektörleri de canlandırır. Daha fazla ticaret, daha yetkin bir sanayi ve daha kaliteli bir hizmet sektörü demektir.
