What are two other names for depletion zone?
In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have been diffused away, or have been forced away by an …
What is the depletion voltage?
When the depletion region reaches metalization, the capacitance remains constant and is called geometric or end capacitance, Cend. The voltage when this occurs is called depletion voltage, Vdep.
Why is depletion region named so in a semiconductor diode?
The depletion region is named so because it is formed from a conducting region by removal of all free charge carriers, leaving none to carry the current. Thus, the positive charge carriers that are crossing the depletion region carry the electric current from one point to another point in the p-n junction diode.
What does depletion region mean?
Depletion region. In semiconductor physics , the depletion region, also called depletion layer, depletion zone, junction region, space charge region or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have diffused away, or have been forced away by an electric field.
What is depletion capacitance?
Depletion Capacitance: The junction capacitance is overriding under the conditions of reverse-bias and the charge storage capacitance is overriding if the junction is forward biased. In several applications of p-n junctions, for usefulness of the device the capacitance is a limiting factor.
What is depletion layer?
depletion layer. n. (Electronics) electronics a region at the interface between dissimilar zones of conductivity in a semiconductor, in which there are few charge carriers.
