These substances exhibit Shockley-Read-Hall and Auger [oh-ZHAY] recombination. One type has a temperature dependence governed by Fermi-Dirac statistics. The intrinsic type has a small but non-zero band gap between the valence and conduction bands. Charge carriers in these materials include both electrons and holes. Their Fermi levels change after adding boron or phosphorous impurities through doping, producing their p and n types. Used in diodes and solar panels, some examples include germanium and silicon. For 10 points, name these materials with conductivities between those of conductors and non-conductors.
