Nature Materials study: Boosting heat transfer with nanoglue
Date:12/4/2012

ics, lighting, and energy generation," said co-author Masashi Yamaguchi, associate professor in the Department of Physics, Applied Physics, and Astronomy at Rensselaer.

This study was funded with support from the National Science Foundation (NSF).

"The overarching goal of Professor Ramanath's NSF-sponsored research is to elucidate, using first-principles-based models, the effects of molecular chemistry, chemical environment, interface topography, and thermo-mechanical cycling on the thermal conductance of metal-ceramic interfaces modified with molecular nanolayers," said Clark V. Cooper, senior advisor for science at the NSF Directorate for Mathematical and Physical Sciences, who formerly held the post of program director for Materials and Surface Engineering. "Consistent with NSF's mission, the focus of his research is to advance fundamental science, but the potential societal benefits of the research are enormous."

"This is a fascinating example of the interplay between the physical, chemical, and mechanical properties working in unison at the nanoscale to determine the heat transport characteristics at dissimilar metal-ceramic interfaces," said Anupama B. Kaul, a program director for the Division of Electrical, Communications, and Cyber Systems at the NSF Directorate for Engineering. "The fact that the organic nanomolecular layer is just a monolayer in thickness and yet has such an important influence on the thermal characteristics is truly remarkable. Dr. Ramanath's results should be particularly valuable in nanoelectronics where heat management due to shrinking device dimensions continues to be an area of active research."
