Multiple choice

The figure shows the high-frequency capacitance-voltage (C-V) characteristics of a Metal/SiO2 /silicon (MOS) capacitor having an area of 1 $\times$10-4 cm2. Assume that the permittivities ($\epsilon_0 \epsilon_r$) of silicon and SiO2 are 1 $\times$ 10-12 F / cm and 3.5 $\times$10-13 F / cm respectively.

The maximum depletion layer width in silicon is

  1. 0.143 $\mu$m
  2. 0.857 $\mu$m
  3. 1 $\mu$m
  4. 1.143 $\mu$m
