Solution

The correct option is C It will change the electron and hole carrier concentrations of the semiconductor
In an intrinsic semiconductor under thermal equilibrium the concentration of dopant affects the concentrations of electrons and holes.
That is,
n=p=n=ni
where,
nconcentration of electrons.
pconcentration of holes.
niIntrinsic concentration at given temperature.
So, when dopant atoms are added to an intrinsic semiconductor, it will change the electrons and holes carrier concentration of the semiconductor.
