Engineers at the UC Riverside have demonstrated prototype devices made of an exotic one-dimensional material that can conduct a current density 50 times greater than conventional copper interconnect ...

A superconducting wire segment based on rare-earth barium copper oxide (REBCO) is the highest performing yet in terms of current density, carrying 190 MA/cm 2 in the absence of any external magnetic ...

However, with electrical gadgets and devices getting increasingly smaller and functionally more powerful, the current density flowing through the copper and gold conductors in these devices – which ...
