A piece of silicon is p-type with a uniform acceptor doping concentration of NA = 6.0e+15 cm-3.
The hole mobility is μp = 457 cm2/V·s.
What are the conductivity and resistivity of this silicon?

If an electric field with strength E = 1.0e+4 V/cm is applied to the material, what is the magnitude of the resulting drift current density?
