Nanocrystalline Copper is Never Flat (video) AMBER Centre Share Print E-Mail Loading video... Caption Professor John Boland from AMBER and Trinity College Dublin's School of Chemistry outlines his team's discovery that nano-sized grains in copper are not flat, but actually tilt up and down to create ridges and valleys within the material. Nanocrystalline metals such as copper are widely used as electrical contacts and interconnects within integrated circuits. This new understanding at the nanoscale will impact how these materials are designed, ultimately enabling more efficient devices, by reducing resistance to current flow and increasing battery life in hand-held devices.
