Researchers from the University of Toronto Engineering in Canada, with assistance from colleagues from Carnegie Mellon University in Pennsylvania, have published new insights into how materials used in electronics transfer heat, which could lead to smaller, more powerful electronic devices capable of more efficient thermal management. According to Dan Sellan and Professor … [Read more...]
Researchers Demonstrate Thermal Invisibility Cloak with Potential for More Effective Heat Management
In recent years, scientists have developed the ability to manipulate light around an object through the use of man-made “metamaterials,” rendering the object seemingly invisible. Now, researchers from the Karlsruhe Institute of Technology (KIT) in Germany have demonstrated the similar ability to manipulate the flow of heat across a sheet of metal to hide a defect in the … [Read more...]
New Method Combines Gallium Nitride and Diamond for Better Thermal Management of Amplifiers
A demonstration of what is considered to be the first-ever gallium nitride (GaN)-on-diamond high electron mobility transistor could significantly reduce thermal resistance and increase RF performance in monolithic microwave integrated circuit (MMIC) power amplifiers, DARPA said in a statement. While MMIC power amplifiers equipped with gallium nitride transistors hold the … [Read more...]
Nanolaser Technology Room-Temperature Breakthrough Could Facilitate Faster Computer Operation
Researchers at Arizona State University have announced a breakthrough in nanolaser technology that could enable electrically-powered nano-scale lasers to perform reliability at room temperature and facilitate their use in a variety of practical applications. While scientists have long believed that nanolasers have the potential to help computers and other electronic devices … [Read more...]
Nanoscale Heat Transfer Research Awarded Air Force Grant
An Arizona State University engineer has been awarded a grant from the U.S. Air Force Office of Scientific Research for nanoscale heat transfer research that could help improve thermoelectric devices and thermal barrier coatings. An assistant professor of aerospace and mechanical engineering at ASU’s School for Engineering of Matter, Transport and Energy, Robert Wang was … [Read more...]
