Abstract
The metal-insulator (M-I) transition in amorphous molybdenum-germanium (a-MoxGel-x) alloys is found at x~0.10. The electrical conductivity measurement has shown exponential behavior due to the variable-range hopping in the insulating and ✓T-dependence in the metallic regime at low temperature. Differential tunneling conductance has shown an anomalous behavior in the tunneling density of states near the Fermi level as a function of energy and composition. Low-temperature specific heat has been measured and indicates there is a finite density of states through the M-I transition. Localization, electron interactions and superconductivity near the M-I transition are discussed.
