A
semiconductor is a solid material that has electrical conductivity between
those of a conductor
and an insulator;
it can vary over that wide range either permanently or dynamically.
A
substance, usually a solid chemical element or compound, that can conduct
electricity under some conditions but not others, making it a good medium for
the control of electrical current. Its conductance varies depending on the
current or voltage applied to a control electrode, or on the intensity of
irradiation by infrared (IR), visible light, ultraviolet (UV), or X rays.
A
semiconductor is a substance, usually a solid chemical element or compound,
that has a conductivity between a metal and an isolator (e.g. Silicon,
Germanium). It's conductivity is adjustable (doping)
making it a good medium for the control of the electrical current.

A
substance such as silicon through which electricity can flow under certain
circumstances. Its conductive properties are between those of a good conductor
and an insulator.
