Problem: Explain how doping silicon with either phosphorus or gallium increases the electrical conductivity over that of pure silicon.
FREE Expert Solution
Silicon is a Group 4A element. It has 4 valence electrons. Pure silicon will use these 4 electrons to form a network with other silicon atoms as shown below:
All the electrons of Si are paired (through more networks of Si atoms). Hence, it is not very conductive at its pure state.
