A piece of silicon is n-type with a uniform donor doping concentration of ND = 4.0e+17 cm-3.
The electron mobility is μn = 403 cm2/Vs.
What are the conductivity and resistivity of this silicon?
A resistor is made using this silicon. The resistor's dimensions are W = 25 μm, L = 80 μm, t = 3 μm.
What is the resistance of the resistor?
