Nano-thermometer enables first atomic-scale heat transfer measurements
Ann Arbor MI (SPX) Jun 17, 2013
In findings that could help overcome a major technological hurdle in the road toward smaller and more powerful electronics, an international research team involving University of Michigan engineering researchers, has shown the unique ways in which heat dissipates at the tiniest scales. When a current passes through a material that conducts electricity, it generates heat. Understanding where the temperature will rise in an electronic system helps engineers design reliable, high-performing computers ... read more
