MCQ
Which is correct statement?
- ASchottky defect occurs when radius of cation is smaller
- ✓When temperature increases then number of defects decreases
- CFrenkel defect occurs when radius of cation is smaller
- DNone of these
✓
Answer
Correct option: B.
When temperature increases then number of defects decreases
As temperature and number of defects are inversely propotional, with increase in temperature number of defects decreases.
In schottky effect, size of ions are almost same while in frenkel defect, size of cation is small.
