In a p type material, the Fermi level is 0.3 eV above valence band. The concentration of acceptor atoms is increased. The new position of Fermi level is likely to be
0.5 eV above valence band
0.28 eV above valence band
0.1 eV above valence band
below the valence band
Correct answer is B
Addition of acceptor atom brings Fermi level closer to valence band.
