A piece of n-type silicon is doped so that the majority carrier concentration is 10^15 cm^-3
What is the minority carrier concentration? (ni = 1.5 x 10^10 cm^-3)
If a piece of silicon is doped with phosphorus to 10^17 cm^-3, what are the equilibrium electron and hole concentrations? (ni = 1.5 x 10^10 cm^-3)
