A semiconductor is used to manipulate the flow of energy within an electronic setting. Semiconductor devices are the many manipulations of this technology to provide a specific control over the energy. These devices are found in many forms and within many types of electronics. Semiconductor devices are comprised of material that can be manipulated easily to control how power reaches an electronic device. Semiconductors can be altered by using an induction of an electric field, exposure to light, pressure and heat. These devices are comprised of material with holes in it, which are positive, or p-type, and material with extra electrons, which are negative, or n-type.
