The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

Optical signals in conventional optoelectronic devices have to be converted into electronic signals when they are amplified or manipulated. But the slow pace of electrons through silicon-based ...

Transistors are at the heart of the electronic circuits that make modern computers possible. Now a transistor that controls the flow of atoms, rather than electrons, could be used as a model to probe ...
