Abstract

The resistance of ultrathin filaments (UF) of Hg (with diameters 20-40 Å) increases as the temperature is lowered as ΔR/R ∼ T -3 2 (T < 60K) and decreases with the applied electrical field as ΔR/R ∼ 1 E. The magnitude 1113 1104 of this effects increases as the diameter of UF is made smaller. Such temperature dependence is interpreted in terms of weak electron localization in one-dimension. The non-linearity of current-voltage characteristics of UF is due to electron-electron interactions in one-dimensional tunnel junctions.
