TL;DR
This study investigates the electrical resistivity of gold-silver nanoparticle coatings across a wide temperature range, exploring low-temperature behavior and potential superconductivity.
Contribution
It provides new insights into the temperature-dependent resistivity of Au-Ag nano-coatings and discusses the possibility of superconductivity in these materials.
Findings
Resistivity varies with temperature from 4.2 K to 300 K.
Features of low-temperature resistance were identified and explained.
Potential for superconductivity in Au-Ag nano-coatings was discussed.
Abstract
The "metallic" temperature variation of the electrical resistivity of chemical nano gold-silver coatings with a silver content of 6.6 % at. up to 13.1 % at. determined in the temperature range 4.2-300 K. Features of low-temperature measurements of the resistance of nano-coatings were found and explained. The possibility of the appearance of superconductivity in them is discussed.
