Abstract

The conductivity of doped Ge below the metal-insulator transition is measured at temperatures between 4 K and 40 mK and in magnetic fields up to 7 Tesla. In zero field the resistivity exponent diverges asT –1/2. In weak fields the magnetoresistance increases asB 2 and becomes exponentially large in strong fields and at low temperatures. The results can be described quantitatively in terms of ...
