Diffusion current - Wikipedia
Webdiffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that … WebOk, so in forward bias the current flow is due to diffusion, owing to concentration differences which in turn is maintained due to recombination. But then, what what is the … eight ball tabletop billiards amazon

WebJul 5, 2024 · The diffusion and larger drift forces will dominate, and majority carriers will cross the junction. The crossing of majority carriers onto the other side is known as … WebMay 16, 2024 · You are right that there are both drift and diffusion currents in the pn-diode. However, due to current continuity in the one-dimensional diode model, the total current (electrons and holes) can be described as the sum of the minority diffusion currents in the quasi-neutral p- and n-regions at the respective depletion zone boundaries. WebEasy Solution Verified by Toppr Correct option is C) During formation of p-n junction p-side has excess holes and n-side has excess electrons. Hence, current tends to flow due to diffusion from p-side to n-side. This does not happen without an external bias because of the potential barrier at the junction. follow up email after long time
