In semiconductor physics, the Depletion Zone or Depletion layer is a nonconductive region within a conductive, doped semiconductor material where the charge carriers have been swept away. Whereas P and N-doped semiconductors are conductors, the Depletion Zone is an insulator. The existence and shape of Depletion Zones is easily controlled by e-fields, i.e. by voltages applied to the electrodes contacting the semiconductor.
A Depletion Zone is essentially an insulator of programmable shape; a nonconducting balloon which invisible grows and shrinks within a block of silicon. Modern electronics is based on transistors, and transistor operation is based on depletion zones.
In semiconductor physics, the depletion region, also called depletion layer or depletionzone, is an insulating region within a conductive, doped semiconductor material where the charge carriers have been swept away through recombination.
The depletion region forms across the P-N junction when the junction is in thermal equilibrium, i.e.
