Crystal Defects: Write a Short Notes on Crystal Defects - BYJU
WebExamine the given defective crystal. Answer the following questions: (i) What type of stoichiometric defect is shown by the crystal? (ii) How is the density of the crystal affected by this defect? (iii) What type of ionic substances show such defect? Answer: (i) Schottky defect. (ii) Density of crystal decreases. WebThe properties of nanomaterials can be tuned by changing the chemical composition and/or the microstructure, such as the size of grains, as well as the type and density of crystal defects inside the grains. Defects disrupt the ideal periodic arrangement of atoms in crystallites. This disruption is known as lattice strain. shepherd smith fired 2019
