Question 7
ECMCQ1 markNeeds review
The energy band diagram of a p-type semiconductor bar of length L under equilibrium condition (i.e., the Fermi energy level
is constant) is shown in the figure. The valence band
is sloped since doping is non-uniform along the bar. The difference between the energy levels of the valence band at the two edges of the bar is
. 
If the charge of an electron is q, then the magnitude of the electric field developed inside this semiconductor bar is
