About this video

A new ‘super plastic’ that can direct heat away from its source opens up a wide range of possibilities for making more efficient electronic devices.

The teams from Associate Professors Jinsang Kim and Kevin Pipe are using hydrogen bonding from two different liquid polymers to regenerate a continuous pathway for heat transfer. These same principles can be used to “fine tune” other thermal properties to design future heat resisting or insulating plastics.

About the Professors

Kevin Pipe is an Associate Professor of Mechanical Engineering at the University of Michigan College of Engineering. He researches Microscale heat transfer, especially related to electronic and optoelectronic devices. He is also Associate Chair for Graduate Education; Associate Professor, Applied Physics Program and Associate Professor of Electrical Engineering and Computer Science.

Jinsang Kim is an Associate Professor of Materials Science and Engineering at the University of Michigan College of Engineering. He researches molecular design, synthesis, modification and self-assembly of smart polymers for biomedical and optoelectronic applications. He also holds Associate Professor titles in Chemical Engineering, Biomedical Engineering, Macromolecular Science and Engineering and Chemistry.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
