Question

Q. How is a P-N Junction obtained? Draw the
diagram of P-N junction and explain the
following terms :
(a) Uncovered charge
(b) Depletion layer
(c) Potential barrier
Ans. P-N junction diode :- When P - type and n -
type semiconductors are joined, they form P-N
junction which works as a diode valve . So it is
popularly known as P-N junction diode. It is
represented by symbol

Answer 1

Answer:

Explanation:

a) Known as uncovered charges, these result in an over-all negative charge in the p-type material and an over-all positive charge in the n-type material. This separation of charges develops a potential across the depletion region, preventing further diffusion of carriers across the junction.
