MOS Capacitor: mode of operation 1
Consider a MOS capacitor with the equilibrium band diagram shown below.

(Drawings made by Julie Kasick)
With a voltage V applied to the gate relatively to the semiconductor, we obtain the following band diagram:

Specify the mode of operation of the MOS capacitor.
The MOS capacitor is in mode.
The gate voltage relatively to the semicondutor is .
Specify the correct answer.
A depletion region is present in the semiconductor.
An inversion region is present in the semiconductor.
An accumulation region is present in the semiconductor.
