Vedclass · Answer

(B) In a $P-N$ junction,there is a built-in potential barrier at the junction due to the diffusion of charge carriers. For a $P-N$ junction,the potential on the $P$-side is higher than the potential on the $N$-side in equilibrium. When the junction is forward biased,the external voltage opposes the built-in potential barrier,reducing the effective barrier height. However,the potential profile across the junction still shows a decrease from the $P$-side to the $N$-side. Graph $B$ correctly represents the potential variation across the $P-N$ junction,where the potential is higher on the $P$-side and lower on the $N$-side.

Which of the following graphs is correct for a $P-N$ junction? (When the $P-N$ junction is forward biased.)
