摘要：

A transition in the resistance behavior of amorphous indium oxide In(x)Oy films from a Coulomb-gap variable-range hopping law towards a constant activation energy law has been observed at low temperatures. The magnetoconductance (MC) is strongly positive, linear in magnetic field, and increases with decreasing temperature as T-1.1 in a fixed magnetic field. The MC theories of Schirmacher and of Nguyen, Spivak, and Shklovskii qualitatively describe the MC data.
