Light Emitting Diodes (LEDs)

A Light emitting diode (LED) is essentially a pn junction diode. When carriers are injected across a forward-biased junction, it emits incoherent light. Most of the commercial LEDs are realized using a highly doped n and a p Junction. Figure 1: p-n Junction under Unbiased and biased conditions.File Size: 927KB

Jul 08, 1980 · In troubleshooting transistor cir- cuits, the most important area to examine is the base-emitter junction as this is the control point of the transistor. If the base-emitter junction is for- ward biased, the transistor would normally be “on.” If the base-emitter junction has zero bias or reverse bias, it should be turned off.
