WebAug 1, 1973 · Electrical conductivity measurements have been made on copper sulfide crystals of compositions ranging from Cu 1.8 S to Cu 2.0 S and indium-doped Cu 1.8 S in the temperature region between 20°C and 220°C. Conductivity of Cu 2-x S varied from 0.07 ohm -1 cm -1 to 2400 ohm -1 cm -1 as the deviation from stoichiometry increased … WebWhen considering other metals with a similiar conductivity profile, silver provides a strong potential alternative. Silver is approximately 7% more conductive than Copper by length. However, longer lengths of silver wire reduce its efficiency as an electrical conductor. It also oxidizes at a faster rate than Copper.
