SUMMARY
The discussion focuses on calculating the resistivity of doped silicon (Si) substrates, specifically comparing phosphorus (P) and arsenic (As) doping. The correct approach involves determining the mobility from a curve based on the total doping concentration, rather than using a simplified formula like \mu_n(N_d + N_d). The total concentration should be calculated as N_{tot} = N_d(P) + N_d(As), but the resistivity calculation is primarily influenced by the highest dopant concentration. For detailed methodology, refer to the provided resource on mobility.
