What is Pyroelectricity or Pyroelectric Material?

Which of the following is a dielectric property of solids?

Assertion : Semiconductors are solids with conductivities in the intermediate range from ${10}^{-6}-{10}^4 {\mathrm{ohm}}^{-1} {\mathrm{m}}^{-1}.$

Reason : Intermediate conductivity in semiconductor is due to partially filled valence band.
