WebP-n junctions are formed by joining n -type and p -type semiconductor materials, as shown below. Since the n -type region has a high electron concentration and the p -type a high hole concentration, electrons diffuse from the n -type side to the p -type side. Similarly, holes flow by diffusion from the p -type side to the n -type side. WebNovember 21, 2024 - 733 likes, 74 comments - Andrea Pico Estrada (@andreapicoestrada) on Instagram: "Take a leap!!
