Solutions of diffusion equation for point defects
An analytical solution of the equation describing diffusion of intrinsic point defects in semiconductor crystals has been obtained for a one-dimensional finite-length domain with the Robin-type boundary conditions. The distributions of point defects for different migration lengths of defects have been calculated. The exact analytical solution was used to verify the approximate numerical solutio...
متن کاملPOINT DEFECTS IN FeAl
Point defects in annealed B2-phase FeAl samples in the range 47-53 at.% Fe were studied using 57Fe Mössbauer spectroscopy. Spectra were analyzed using local environment models according to which point defects in atomic shells close to probe atoms induce shifts in the nuclear monopole interaction. For well-annealed samples, better results were obtained assuming only the presence of FeAl antisite...
متن کاملElimination of Defects of Meromorphic Mappings of C into P(c)
The Nevanlinna defect relation and other results on the Nevanlinna theory assert that each meromorphic mapping f of C into P(C) has few deficient hyperplanes in P(C) . However, it seems to me that meromorphic mappings with a deficient hyperplane must be very few. In this paper, we show that for an arbitrary given transcendental meromorphic mapping f (which may be linearly degenerate), we can el...

متن کاملStability of Si-interstitial defects: from point to extended defects
Trends in the growth of extended interstitial defects are extracted from extensive tight-binding and ab inito local density approximation simulations. With an increasing number of interstitials, the stable defect shape evolves from compact to chainlike to rodlike. The rodlike 311 defect, formed from (011) interstitial chains, is stabilized as it grows, elongating in the chain direction. Accurat...
