抄録

The electrical conductivities of Co thin films with the thickness in the range 2.530 nm have been studied. In the low temperature region, the sheet conductivities for the films of 3.05.0 nm show logarithmic temperature dependence. The dependence is interpreted by the electron-electron interaction effect rather than the weak localization effect. The coefficient of the logarithmic behavior is found to be suppressed as the thickness decreases, which may be interpreted in terms of the percolation effect.
