A 3" diameter germanium wafer that is 0.020" thick at 300K has 3.419*10^17 As atoms added to it. What is the resistivity of the
wafer? Germanium has 4.42*10^22 atoms/cc, electron and hole mobilities are 3900 and 1900 cm^2/(V*s). What is the resistivity of the Ge in ohm*microns? Three significant digits and fixed point notation.
