A silicon sample is 85x10^-6 m in length and has a cross-section of 20x10^-6 m x 6x10^-6 m. It has been uniformly doped with Arsenic with a doping density of 4.5x10^15 cm^-3. Assume the temperature is 300K and mobilities are u_n = 1300 cm^2/Vs and u_p = 450 cm^2/Vs.
a. What are the majority and minority carrier concentrations?
b. What is the resistivity of the sample?
c. What is the resistance (end-to-end) of the sample?
