Question

Silicon is doped with boron to a concentration of 4 x 1017 atoms/cm3. Assuming the intrinsic carrier concentration of silicon to be 1.5 x 1010/cm3 and the value of  to be 25mV at 300K. Compared to undoped silicon, the Fermi level of doped silicon-A-goes down by 0.13 eVB-goes up by 0.13 eVC-goes down by 0.427 eVD-goes up by 0.427 eV-C-goes down by 0.427 eV

APTITUDE CRACK · Accepted Answer

C goes down by 0.427 eV  Use EF Ev = Since it is doped with acceptor impurity, Fermi level will shift down.
