Laptop computers can generate enough heat that, in rare cases, they actually catch fire. While engineers have a great grasp of how to control electrical charge in circuits, they have a hard time getting rid of the heat created by flowing electrons. Whats missing is a fundamental understanding of how individual electrons generate heat.
A new device developed by University of Wisconsin-Madison Electrical and Computer Engineering Associate Professor Robert Blick promises to change that. In addition, it will provide insights into harnessing quantum forces for communication and computing.
Blick, along with his graduate student Eva Hoehberger and colleague Werner Wegscheider, developed something similar to an incredibly small trampoline for bouncing individual electrons. It operates as an artificial atom, or a membrane, suspended over a semiconductor cavity.
