What are the limitations, if any, on (a) forward bias, (b) reverse bias of a junction diode?
p-n junction From Wikipedia, the free encyclopedia Jump to: navigation, search A p-n junction is a junction formed by combining P-type and N-type semiconductors together in very close contact. The term junction refers to the region where the two regions of the semiconductor meet. It can be thought of as the border region between the p-type and n-type blocks as shown in the following diagram: A silicon p-n junction with no applied voltage.The most common type of solar cell is basically a large p-n junction; the free carrier pairs created by light energy are separated by the junction and contribute to current. A common type of transistor, the bipolar junction transistor, consists of two p-n junctions in series, for example in the form n-p-n; no current can flow through it unless a separate small voltage is applied to the middle layer. The invention of the p-n junction is usually attributed to Russell Ohl, Bell Laboratories. Contents [hide] 1 Manufacture 2 Properties of a p-n junction 3 E
