Localization effects in thin potassium wires

A min. in the electrical resistivity as a function of temp. was recently observed in pure thin potassium wires near 1K. This effect is interpreted in terms of inelastic-scattering events interrupting the coherence of one-dimensional localized electrons. Assuming that a min. energy transfer is requir...

Description
Summary:A min. in the electrical resistivity as a function of temp. was recently observed in pure thin potassium wires near 1K. This effect is interpreted in terms of inelastic-scattering events interrupting the coherence of one-dimensional localized electrons. Assuming that a min. energy transfer is required for a collision to be effective, either electron--electron scattering or electron--phason scattering could be the appropriate inelastic mechanism. 15 ref.--AA
