The impurity to be mixed in pure Germanium in order to make it a p−type semiconductor is________
The impurity to be mixed in pure Germanium in order to make it a p−type semiconductor is________
Open in App
Solution
The correct option is C Aluminium
p-type semiconductor has holes as the majority charge carriers. Thus when a pure Germanium semiconductor is doped with the impurity of trivalent elements like Aluminium or Boron, it gets converted into a p-type semiconductor.
