We create a pn-junction by joining together two pieces of semiconductor,one doped n-type,the other p-type. This causes a depletion zone to form around the junction(the join)between the two materials. This zone controls the behavior of the diode....

Since this is the main symbol for the diode, the symbol gets changed according to the other available functioning diodes. What are the Purposes of PCB Diodes? The main function of PCB diodes in the industry is as follows. A diode works based on the PN junction's unidirectional conductivity....
The pn Junction and the Diode Get some semiconductor-grade silicon (thereallypure stuff). Dope a section of it with a pentavalent element to make n-type silicon, and dope an adjacent section of it with a trivalent element to make p-type silicon. You’ve got a pn junction—one of the ...
The basic structure of a crystal diode is a combination of a P-type semiconductor and an N-type semiconductor that form a PN junction. At the interface of the PN junction, since the holes in the P-type semiconductor and the electrons in the N-type semiconductor are to diffuse to each ot...
PN Band/ Saumitra R Mehrotra & Gerhard Klimeck / CC BY This p-n junction is incredibly important in solid state electronics. In fact, the system we just described can be used as a diode, which is a device that only allows current to flow in a single direction. If a battery is connect...
Diode representations: PN-junction model, schematic symbol, physical part.The schematic symbol of the diode is shown in the figure above (b) such that the anode (pointing end) corresponds to the P-type semiconductor at (a). The cathode bar, non-pointing end, at (b) corresponds to the N...
Because the semiconductor diode has the characteristic of unidirectional conduction, the PN junction is turned on under positive bias, and the resistance in the on-state is very small, about tens to several hundred ohms; under reverse bias, it is turned off. Its resistance is very large. ...
