Effect of Restricted Diffusion of Trapped Interstitials on the Central Shift of Mössbauer Impurities
نویسندگان
چکیده
The central shift of 57Fe atoms with trapped interstitials (mixed dumbbells) in aluminium increases steeply at temperatures between 10 and 20 K. Influences of restricted diffusion of the Mossbauer atom in a cage on the isomer shift and second order Doppler shift are discussed.

Intrinsic Point Defects and Impurities in Silicon Crystal Growth
The incorporation of intrinsic point defects into a growing crystal is affected by the presence of impurities that can react with vacancies and self-interstitials. The critical value of the ratio of the growth rate, V , to the axial temperature gradient, G, ~V/G ratio! that separates the interstitial growth mode from the vacancy growth mode, is shifted by impurities, and this effect can be desc...

متن کاملSolutions 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...

In this work, we have studied the miniband and minigaps of GaN/AlN constant total effective radius multi-shells quantum dots (CTER-MSQDs) and Rings (CTERMSQRs).We have investigated effects of the Hydrogenic donor impurities, quantum dots and rings radii, and the number of wells on miniband formation by sub-band energy calculations. We show that in these systems, minigaps can be created and then...
