semiconductor Definition

semi·con·duc·tor (sem′i kən duk′tər)

noun

a substance, as germanium or silicon, whose conductivity is poor at low temperatures but is improved by minute additions of certain substances or by the application of heat, light, or voltage: used in transistors, rectifiers, etc.

semiconductor Telecom Definition

A material that is neither a good conductor of electricity nor a good insulator, but has properties of electrical conductivity somewhere between the two. Silicon and germanium are good semiconductor materials. Dopants such as arsenic and antimony sometimes are introduced during the manufacturing process to alter the performance characteristics of the semiconductor. See also conductor, dopant, and insulator.
