Germanium photoresistance is illuminated with monochromatic radiation, which is uniformly absorbed throughout the entire volume. The resistivity of the sample is 45 Ohm•cm, the concentration of electrons and holes increases due to illumination by 1017 m-3. The electron and hole mobilities are me = 0.38 m2/(V•s) and mp = 0.18 m2/(V•s). What is the relative change in electrical conductivity of the germanium plate?
