Final Answer:
The given statement the depletion region lies between the n-type and p-type semiconductors in a pn junction is true
Step-by-step explanation:
In a pn junction, when a p-type semiconductor (with positive charge carriers or "holes") is brought into contact with an n-type semiconductor (with negative charge carriers or electrons), a depletion region is formed at the junction between them. This region is devoid of free charge carriers and is created due to the diffusion of charge carriers from one side to the other.
The depletion region acts as a barrier, preventing further diffusion of charge carriers and establishing an electric field. This electric field opposes the further movement of charge carriers across the junction. As a result, an equilibrium is reached where the movement of charge carriers due to diffusion is balanced by the electric field.
The width of the depletion region is influenced by factors such as the doping concentrations in the n-type and p-type semiconductors. Understanding the characteristics of the depletion region is crucial in the operation of semiconductor devices such as diodes and transistors.
In summary, the statement is true—the depletion region lies between the n-type and p-type semiconductors in a pn junction, playing a vital role in the behavior of semiconductor devices.
