The number of silicon atoms per $m^3$ is $5 \times 10^{28}$ This is doped simultaneously with $ 5 \times 10^{22}$ atom per $m^3$ of and $ 5 \times 10^{26}$ per $m^3 $ atoms of indium . Calculate the number of electrons and holes . Given that $n_i=1.5 \times 10^{16}\;m^{-3}$. material n -type or p type
