A piece of silicon is n-type with a uniform donor doping concentration of NN = 4.0e+17 cm-3.
The electron mobility is μn = 287 cm2/V·s.
What are the conductivity and resistivity of this silicon?
You would like to make rectangular resistor with value R = 10 kΩ in this silicon.
The resistor's cross-sectional dimensions are: W = 8 μm and t = 1.14 μm.
What length should the resistor have?
