A piece of silicon is p-type with a uniform donor doping concentration of N_A = 8.0e+17 cm^-3.
The hole mobility is μ_p = 110 cm²/Vs.

What are the conductivity and resistivity of this silicon?

A resistor with resistance R = 5 kΩ will be made using this silicon.
The resistor's length is L = 900 μm and the thickness is t = 5 μm.
How wide should the resistor be?
