vacancies (crystal)/ self interstitialsCdtracer self diffusionThe temperature dependence of tracer self-diffusion measurements in cadmium is analyzed in conjunction with investigations of the equilibrium concentration of vacancies by thermal expansion and positron annihilation. The following values for the ...
The aim of this paper is to derive from experimental data reliable information on vacancies and self-interstitials in the hexagonal metals Zn and Cd, in particular on their migration enthalpies, and thus to put on a firm footing the interpretation of further experiments, e.g. in the fields ...
providing a clear explanation of our computational results.Vacancies and self-interstitials (SIAs) significantly enhance Be aggregation, and the optimal configuration for Be clustering in Mo has been identified, with particular attention given to the effects of vacancies and SIAs.This study reveals an ...

Next, we must consider the species that can be present in our films and could lead to PL quenching. There are different species that have been reported to quench the PL in the perovskite film forming effective recombination centers38. Iodide interstitials have been recently highlighted as one pre...
Lattice point defects such as vacancies and interstitials in semiconductors can function as very effective traps for these particles.30 If excitons attached to defects combine again radiatively, light is emitted at energies below the optical band transition energy. Because of the electron wave function...
Designing chemical substitutions13, interstitials14,15, or vacancies16,17in thermoelectrics is a conventional method to strengthen phonon scattering and therefore improve ZT. Recently, the importance of defect chemistry, both intrinsic and extrinsic, in the optimization of thermoelectric properties has been...
The difference between the enthalpy and energy of formation becomes noticeable only at high pressures. Formation enthalpies of interstitials are larger than those of vacancies, so vacancies are the dominated point defects. Along with monovacancies, vacancy clusters of various sizes exist under equilibrium...
This article aims to review in rather cursory fashion the ways the concepts of lattice defects have contributed at an early stage to our understanding of solid-state kinetics in metals and insulators. The importance of point defects in solid-state kinetics was just beginning to be widely ...
