Question 32
ECMCQ2 marksNeeds review
The band diagram of a
-type semiconductor with a band-gap of 1 eV is shown. Using this semiconductor, a MOS capacitor having
of
V,
of
nF/cm
and a metal work function of 3.87 eV is fabricated. There is no charge in the oxide. If the voltage across the capacitor is
, the magnitude of depletion charge per unit area (in C/cm
) is
