A SIMPLE TECHNIQUE FOR MEASURING DOPING EFFECTS ON DISLOCATION MOTION IN SILICON

A Contactless Technique for Measuring Minority-carrier Parameters in Silicon

Characterization of minority-carrier parameters is a primary interest for a range of devices, including solar cells. For “on-line” testing needs, contactless techniques are mandatory, as any diagnostic requiring contact formation is impractical. Here, we will describe the resonancecoupled photoconductive decay (RCPCD) technique that has proven to be a valuable diagnostic for a number of semicon...

Temperature effects on dislocation core energies in silicon and germanium

Temperature effects on the energetics of the 90◦ partial dislocation in silicon and germanium are investigated, using non-equilibrium methods to estimate free energies, coupled with Monte Carlo simulations. Atomic interactions are described by Tersoff and EDIP interatomic potentials. Our results indicate that the vibrational entropy has the effect of increasing the difference in free energy bet...

Dislocation motion in silicon: the shuffle-glide controversy revisited

Considering recently computed formation and migration energies of kinks on non-dissociated dislocations, we have compared the relative mobilities of glide partial and shuffle perfect dislocations in silicon. We found that the latter should be more mobile over all the available stress range, invalidating the model of a stress driven transition between shuffle and glide dislocations. We discuss s...

I-4: A Simple and Safe Technique for Varicocele Surgery

s:2127:"Varicocele is the most common pathologic finding in men in infertility study programs and is the most treatable cause of male infertility. Its correction is performed by different surgical techniques, none of which is yet acknowledged as the "gold standard." Some of them, especially the microsurgical ones, are very time consuming and thus expensive; furthermore, all varicocele surgery i...
