Regarding a semi-conductor which one of the following is wrong ?
Text Solution
Verified by ExpertsThe correct answer is:
B
In semiconductor, no covalent bond breaks at 0 K, so, no electron is free at 0 K. At room temperature some covalent bonds break, so, some electrons and holes become free. More covalent bonds break at high temperature and so, number of free electrons increases at high temperature.
