The P-N Junction

The P-N Junction

Merely connecting up a piece of semiconducting material, either P or N type, to a source of current can be interesting, and a good subject for science experiments. But when the two types of...

Doping and Charge Carriers

Doping and Charge Carriers

For a semiconductor material to have the properties necessary in order to function as electronic components, impurities are usually added. The impurities cause the material to conduct currents in certain ways. The addition of...

Semiconductor Materials

Various elements, compounds, and mixtures can function as semiconductors. The two most common materials are silicon and a compound of gallium and arsenic known as gallium arsenide (often abbreviated GaAs). In the early years...

The Semiconductor Revolution

The Semiconductor Revolution

Decades ago, vacuum tubes, also known as electron tubes, were the only devices available for use as amplifiers, oscillators, detectors, and other electronic circuits and systems. A typical tube (called a valve in England)...
