semiconductor

semiconductor

[-kənduk′tər]

a solid crystalline substance whose electric conductivity is intermediate between that of a conductor and that of an insulator. An n-type semiconductor has loosely bound electrons that are relatively free to move about inside the material. A p-type semiconductor is one with holes, or positive traps, in which electrons may be bound. The holes may appear to migrate through the material.
