☑ Pn Junction Animation

Free electrons on the n side and free holes on the p side can initially wander across the junction. P n junctionwhen a p type semiconductor is suitably joined to n type semiconductor the contact surface in called p n junctionconsider two types of materialsone p type and the other n type as.

An attractive animation is presented in this video with complete voice description.

Pn junction animation. Zero biased junction diodewhen a diode is connected in a zero bias condition no external potential energy is applied to the pn junction. P n junctions are formed by joining n type and p type semiconductor materials as shown belowsince 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 sidesimilarly holes flow by diffusion from the p type side to the n type side. A pn junction is formed 2.

P n junctions formation of a p n junction. It will help you to grasp concepts behind pn junction even better. Diodes what are diodes pn junction.

How does a p n junction diode works. When a free electron meets a free hole it can drop into it. It can function as.

Explained through animation. However if the diodes terminals are shorted together a few holes majority carriers in the p type material with enough energy to overcome the potential barrier will move across the junction against this barrier potential. This is a physics video for grade 11 12 students about p n junction diode its properties characteristics and uses.

You do watch this video. Pn junction diode 1. I have developed a second chapter on the series which explains the characteristics of pn junction diode.

Pn junction formation explained using animations. P type and n type semiconductors takenseparately are of very limited useif we join a piece of p type material to a pieceof n type material such that the crystalstructure remains continuous at the boundary. You can read the article here pn junction diode and its characteristics.

Pn junction diode consider a p type material and n type material are brought together to form a pn junction diode. The combination of p type and n type semiconductors results in a junction.
