How is a pn junction formed
WebPN Junctions: Overview The most important device is a junction between a p-type region and an n-type region When the junction is first formed, due to the concentration … Web23 dec. 2024 · When a p-n junction is formed, some of the free electrons in the n-region diffuse across the junction and combine with holes to form negative ions. In so doing they leave behind positive ions at the donor impurity sites. In my mind, the diffusion of electrons causes holes in the p-type region near the junction to be filled.
