Researchers at the Carnegie Institution recently discovered a new efficient way to pump heat using crystals. The crystals pump or extract heat, even on the nanoscale, which means they could be used to overcome current constraints to higher computer speeds by providing a solution to chip overheating. Ronald Cohen, staff scientist at Carnegie’s Geophysical Laboratory and Maimon Rose, led the team that carried out the research. They performed simulations on ferroelectric crystals—materials that have electrical polarization in the absence of an electric field. The electrical polarization is reversed by applying an external electrical field. Introducing an electric field causes a giant temperature […]
