(B). Draw the band diagram for an InP crystal (Eg=1.35eV,ni=1107cm3,mn=0.077m0,mh= 0.64m0 ) doped with ND=51013cm3 at T=300K, assuming complete ionization. Note the energy difference between Ef to Ei and Ec to Ef. Label the conduction band (Ec), the valence band (Ev), Fermi level (Ef), and intrinsic level (Ei). Note: since mn=mh, the intrinsic level is NOT at the mid-gap; you must calculate its relative position. (C). Repeat (B) for the doping concentrations noted below. Describe how Ef changes as the doping concentration increases. i. ND=51014cm3 ii. ND=51015cm3
