6 Questions
What creates the space charge (depletion) region of width W?
Electric field E established from the fixed +ve ions (N + d ) and -ve ions (N − a).
What happens when p-type and n-type are put together?
Holes diffuse from p-side to n-side and electrons from n-side to p-side.
What does the electric field E induce across the depletion region?
Drift current to oppose diffusion current.
What creates the space charge (depletion) region of width W when p-type and n-type are put together?
Migration of carriers (holes and electrons)
What type of current does the electric field E induce to oppose the diffusion current across the depletion region?
Drift current
What establishes an equilibrium potential difference V0 across the width W of the depletion region?
The electric field E
Test your knowledge about the PN junction and the establishment of an electric field. Understand the process of carrier diffusion, space charge region, and the creation of drift current.
