extrinsic semiconductor

[ek¦strinz·ik ′sem·i·kən‚dək·tər]
(electronics)
A semiconductor whose electrical properties are dependent on impurities added to the semiconductor crystal, in contrast to an intrinsic semiconductor, whose properties are characteristic of an ideal pure crystal.

We choose n-Si because it is a strongly dispersive extrinsic semiconductor. Its dielectric function is strongly dependent on the doping density.

Here, the semiconductor will be taken to an extrinsic semiconductor, n-Si whose permittivity can be tuned by the impurity concentration.
