WebMar 20, 2024 · 3) Alkali halides like CsCl, NaCL, etc. do not show the Frenkel defect. > Since in NaCl, KCl the size of anions and cations are similar, they do not show Frenkel defects. > In CsCl and AgCl, there is a large difference in the size of anions and cations , but CsCl being an alkali halide does not show Frenkel defect. So only AgCl shows … WebMetal excess defect due to anionic vacancies: Alkali halides like NaCl and KCl show this type of defect. When crystals of KCl are heated in an atmosphere of potassium vapour, the Potassium atoms are deposited on the surface of the crystal. The Cl– ions diffuse to the surface of the crystal and combine with K atoms to give KCl.

WebNov 15, 2024 · High-quality CsPbI 2 Br film grown with CsCl reveals high crystallinity and largely-grained morphology, which provides reduced defect density and energy loss. As a result, we optimize the CsPbI 2 Br device with 1% CsCl additive, which shows a power conversion efficiency (PCE) of 11.04% with an open-circuit voltage (V OC) of 1.33 V. WebMar 3, 2012 · 1.Frenkel defect-This defect is shown by those ionic solids which there is a large difference in the size of ions e.g.ZnS,Agcl,AgBr. 2.Schottky defect-It is a stoiciometric defect in which equal number of anions and cations are missing from their lattice sites substances in which the cation and anion of almost similar size e.g.NaCl,KCl,CsCl … WebSchottky defect is a type of point defect in which vacancies of ions occur at some points in the crystal lattice. This defect is stoichiometric in nature i.e., the stoichiometry of the crystal does not change with this defect as the number of cations and anions that are missing … tti annual report 2020
