Silicon is doped an acceptor of 10^18/cm^3. Find the electron and hole concentration, the electron and hole mobilities, and the resistivity of this silicon material at 300 K. Is this n-type or p-type?
You might find the equation you need at
The previous reference I provided won't help you. It is for intrinsic silicon only.
There is a discussion of doped semiconductor electron and hole concentrations at
Good luck. This is not my field of expertise
