Vedclass · Answer

(B) When a $P-N$ junction is formed,electrons diffuse from the $N$-region to the $P$-region due to the concentration gradient. This diffusion leaves behind immobile positive ions in the $N$-region and negative ions in the $P$-region near the junction. This creates an electric field directed from the $N$-region to the $P$-region. Consequently,the potential of the $P$-region becomes higher than that of the $N$-region,creating a potential barrier.
