Is displacement current flow in diode?

Displacement current does not flow in a diode in the same way that conventional current does. In a diode, current primarily consists of the flow of charge carriers (electrons and holes) under the influence of an electric field. Displacement current is a concept used in the context of changing electric fields, particularly in capacitors, and it complements the conduction current in situations where the electric field is time-varying. However, in a standard diode operation, it is the conduction current that dominates.
