Resistivity & Mobility Calculator/Graph for Various Doping Concentrations in Silicon Dopant: Arsenic Boron Phosphorus Impurity Concentration: (cm-3) Mobility: [cm2/V-s] Resistivity: [Ω-cm] Note: Calculations are for a silicon substrate. Arsenic and Phosphorus provide electron mobilities, Boron provides hole mobility. Source: G. Masetti, M. Severi, and S.
