A piece of silicon is p-type with a uniform acceptor doping concentration of NA = 8.0e+18 cm-3.
The hole mobility is μp = 51 cm2/V·s.
What are the conductivity and resistivity of this silicon?
A rectangular resistor is made in this silicon.
The resistor dimension are: W = 3 μm, L = 15 μm, t = 0.375 μm.
What is the resistance of the resistor?
