प्रश्न
Write a short note on diffusion current across the p-n junction.
उत्तर
When a p-n junction is formed, holes diffuse from the p-side to the n-side while electrons diffuse from the n-side to the p-side. This result due to the concentration gradient across p and n sides, which gives rise to a diffusion current across the junction.
