LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is ...

The diagram illustrates the basic structure of a p-n junction diode with p-type silicon on one side, n-type silicon on the other, and the anode and cathode terminals. It also includes the symbol for a ...

Last week we covered diodes, specifically thermionic and PN junction diodes ... techniques allow us to directly bond a metal cathode to silicon, creating a larger contact area than a pointed ...

It has two points of contact, or terminals, called its anode and cathode. A diode’s primary purpose is to allow current to flow in only one direction. It achieves this using a p-n junction.
