Draw the energy band diagrams of \[n\] -type and p-type semiconductors. A semiconductor has equal electron and hole concentration of \[6\times {{10}^{4}}{{m}^{-3}}\]. 0" doping with a certain impurity, electron concentration increases to \[8\times {{10}^{12}}{{m}^{-3}}\]. Identify the type of the semiconductor.                                

Answer:

                                                                                As the electron concentration becomes greater than the hole concentration on doping, the resulting semiconductor is of n-type.
