A shield for 2D materials that adds vibrations to reduce vibration problems

A new study demonstrates a new, counterintuitive way to protect atomically-thin electronics -- adding vibrations, to reduce vibrations. By squeezing a liquid-metal gallium droplet, graphene devices are painted with a protective coating of gallium-oxide that can cover millimeter-wide scales, making it potentially applicable for industrial large-scale fabrication. The new technique improves device performance as well as protecting 2D materials from thermal vibration in neighboring materials.
