A semi conductor is a material that is not such a good conductor as a metal but better than an insulator, this is because it does not contain many free electrons. Silicon and Germanium are examples of semi conductors.Silver ≈ 10-8 ΩmGermanium ≈ 10 ΩmGlass ≈ 109 ΩmThe resistivity of a semi conductor can be reduced by adding impurity atoms to the material, this is called doping. There are two different ways this...
