WebThe application of band theory to n-type and p-type semiconductors shows that extra levels have been added by the impurities. In n-type material there are electron energy levels near the top of the band gap so that they can be easily excited into the conduction band. In p-type material, extra holes in the band gap allow excitation of valence ... WebAnswer As n e n h thus resulting semiconductor is of n type 3 Why is a.
