A piece of silicon is p-type with a uniform donor doping concentration of N_A = 9.0e+17 cm^-3.
The hole mobility is μ_p = 105 cm²/Vs.

What are the conductivity and resistivity of this silicon?

A resistor with resistance R = 4 kΩ will be made using this silicon.
The resistor's cross-sectional dimension are W = 10 μm and t = 3 μm.
How long should the resistor be?
