Vedclass · Answer

(A) In an intrinsic semiconductor,the number of free electrons $(n_e)$ is equal to the number of holes $(n_h)$ at any temperature above $0 \ K$. At room temperature,thermal energy is sufficient to break some covalent bonds,creating electron-hole pairs. Since each broken bond generates one free electron and one hole,the concentration of electrons $(n_e)$ and holes $(n_h)$ remains equal,i.e.,$n_e = n_h = n_i$,where $n_i$ is the intrinsic carrier concentration.

In an intrinsic semiconductor at room temperature,the number of electrons and holes are:
