A piece of silicon is p-type with a uniform acceptor doping concentration of NA = 5.0e+15 cm-3.
The hole mobility is μp = 463 cm2/V·s.
What are the conductivity and resistivity of this silicon?
You would like to make rectangular resistor with value R = 39 kΩ in this silicon.
The resistor's length is L = 30 μm and the thickness is t = 2 μm.
What width should the resistor have?
