When we dope pentavalent in semiconductor,it will introduce a allowable energy level below the conduction band
when dope a trivalent atom ,it will introduce a allowable energy level above valence band.

But why, why will have a energy level in between (below and above) ??
i cant figure it out, someone help me pls
