New research on graphene could lead to more energy-efficient and longer-lasting computers. A research team from Chalmers University of Technology has used a graphene layer to cool tiny hotspots that have normal working temperatures ranging from 55 degrees to 115 degrees Celsius.
"We have been able to reduce this by up to 13 degrees, which not only improves energy efficiency, it also extends the working life of the electronics," says Chalmers professor Johan Liu, who led the project.
Liu says a thin layer of graphene could reduce the working temperature inside a processor by up to 25 percent. Graphene's heat-dissipating effect could benefit any electronic system that has efficient-cooling issues, but the research could have a particularly big impact on data centers, as cooling often compromises half of all the energy they consume.
"This discovery opens the door to increased functionality and continues to push the boundaries when it comes to miniaturizing electronics," Liu says.
