Heat transfer between materials is focus of new research grant

Abstract:
Managing heat is a major challenge for engineers who work on devices from jet engines to personal electronics to nano-scale transistors.

Led by Kevin Pipe, an assistant professor in the Department of Mechanical Engineering, the team has received a Multidisciplinary University Research Initiative (MURI) award from the Air Force Office of Scientific Research. The research group includes nine scientists and engineers from three universities, including Brown University and the University of California at Santa Cruz.

"The processes by which heat is transferred at interfaces between different materials are poorly understood," Pipe said. "But in many systems, the ability to either efficiently transfer or block heat flow from one material to another is critically important to performance and reliability."

Inefficient heat flow is a main roadblock in the development of lasers and transistors that can attain higher powers. On the other hand, blocking heat exchange can dramatically improve the efficiency of thermoelectric energy conversion for compact power sources.

Pipe's group will use ultrafast lasers in a special X-ray technique developed by David Reis, a team member and associate professor in Physics at U-M. The technique allows researchers to actually watch the vibrations of the atoms that carry heat energy across an interface.
