PN junctions are basic building blocks of many electronic devices and their performance depends on the structural properties of the component ... 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. matthew gollan barrister https://sh-rambotech.com
