Kitchen temperature supercurrents from stacked 2D materials

A 'stack' of 2D materials could allow for supercurrents at ground-breakingly warm temperatures, easily achievable in the household kitchen. An international study opens a new route to high-temperature supercurrents -- at temperatures, as 'warm' as inside your kitchen fridge. (Previously, superconductivity has been difficult even at temperatures as low as -170°C, making superconductivity impractical for many of its most exciting applications.)
