Semiconductors are materials with electrical properties that fall between conductors and insulators. They can be pure elements, like silicon or germanium, or compounds, like gallium arsenide or cadmium selenide. 

Semiconductors are the foundation for electronics, especially computers. They are smaller in size, take up less space, and use less power than vacuum tubes. Because they can be made so small, electrical devices can be made thin and lightweight without compromising processing power. 
A crucial property of semiconductors is the band gap, which is a range of forbidden energies within the material's electronic structure. 
In 1874, Karl Braun discovered and documented the first semiconductor diode effect. In 1901, the first semiconductor device, called "cat whiskers," was patented.
