Unlike metals, semiconductors increase their conductivity as you heat them (up to a point). Suggest an explanation. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer
Semiconductors have valence band and conduction band, separated decreases by a characteristic difference in energy, the band gap. When a semiconductor is heated electrons have sufficient energy to jump the band gap, and conductivity Metals have the average kinetic energy of the metal atoms, usually through increased vibrations more continuous energy band. Heating a metal an empty a partially filled within the lattice. The lattice and discontinuities in the energy band. Thermal vibrations create barriers to electron delocalization. This vibrational energy of the atoms leads to imperfections in the less lower the conductivity of the metal.
