The Chip Semiconductors Metal conducts electricity; rubber doesn't. Gold conducts electricity; Styrofoam doesn't. Most materials fall easily into one category or the other. Everyone knows, for example, that if you want a good wire you're going to make it out of copper, not plastic. But there's a whole group of materials that fall in between. Their conductivity is in between metals and insulators. And their conductivity can be modified transiently, by shining a light on them or injecting charges. They're known as semiconductors, and they first became interesting to physicists in the late 1920s. At first no one could figure out how they worked. Scientists once thought that certain atoms simply held onto their electrons more strongly than others. But as physicists got a better understanding of what an atom looked like, they understood what was really going on.

In some cases we'll be dealing with some rather technical terms, and we will sometimes have to deal with some essential concepts involved in physics. More general explanations and definitions will also be given, so if you don't need the technical definitions, don't worry about them. The terms are present in case you actually need them.

Intrinsic Semiconductor A silicon crystal is different from an insulator because at any temperature above absolute zero temperature, there is a finite probability that an electron in the lattice will be knocked loose from its position, leaving behind an electron deficiency called a " hole If a voltage is applied, then both the electron and the hole can contribute to a small current flow. The conductivity of a semiconductor can be modeled in terms of the band theory of solids. The band model of a semiconductor suggests that at ordinary temperatures there is a finite possibility that electrons can reach the conduction band and contribute to electrical conduction. The term intrinsic here distinguishes between the properties of pure "intrinsic" silicon and the dramatically different properties of doped n-type or p-type semiconductors.
