An Unexpected Clue to Thermopower Efficiency


July 28, 2011

vortices fields Scientists at Lawrence Berkeley National Laboratory and their colleagues at the University of California and Nanjing University have discovered a new relation among electric and magnetic fields and differences in temperature, which can result in swirling vortices of electrons and holes in semiconductor devices and emit sideways magnetic fields. Understanding the unusual new effect may lead to more efficient thermoelectric devices, which convert heat into electricity or electricity into heat. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
