Which Phenomenon Explains The Formation Of Pn Junction?

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. WebA pn junction photodiode is shown in Figure 5. The photodiode is formed by boron (p)- and phosphorus or arsenic (n)-doped areas in the single-crystal silicon. If a voltage is applied between the p and the n contact in reverse bias, typically between 1 and 5 V, a depletion layer is formed. hochwind bad aibling https://bigwhatever.net
