sem·i·con·duc·tor

(sem'ē-kon-dŭk'tŏr),
A metalloid that conducts electricity more easily than a true nonmetal but less easily than a metal, for example, silicon, germanium.

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.

semiconductor,

n an object that conducts electricity less than a conductor does but more an insulator does.
