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 کاملComputing Diffusion Coefficients of Intrinsic Point Defects in Crystalline Silicon
The quality of crystalline silicon highly influences the quality of semiconductor devices fabricated with it. Grown-in defects, such as octahedral voids or networks of large dislocation loops can be detrimental to the functionality of devices. Both type of defects result from the interaction of intrinsic point defects, vacancies and self-interstitials during growth and subsequent annealing of t...

متن کاملPrediction of Diffusion Coefficients in Plastic Materials
Plastics properties can be tailored through control of their syntheses and processing to fit every desired application, packaging beeing a major one. Measurable residual amounts or conversion products from the many different raw materials and processing aids used in the various plastic synthesis processes can remain in the finished material along with many chemically different additives which a...
متن کاملMathematical modeling of point defects in materials science
We survey some recent mathematical works we have contributed to that are related to the modeling of defects in materials science at different scales. We emphasize the similarities (need of a reference, often periodic system; renormalization procedure; etc) shared by models arising in different contexts. Our illustrative examples are taken from electronic structure models, atomistic models, homo...
