Germanium is a group 4a semiconductor. the addition of a dopant atom (group 3a element) that has fewer valence electrons than the host atom results in a p-type semiconductor. the addition of a dopant atom (group 5a elements) that has more valence electrons than the host atom results in an n-type semiconductor. which of the following elements when used for doping germanium will yield p-type semiconductors, and which elements when used for doping germanium will yield n-type semiconductors?
