Hitting semiconductors with a superfast electric pulse massively…


Researchers from Kyoto University have discovered a new technique that could dramatically improve the efficiency of some semiconductors. They took gallium arsenide, and blasted it with a terahertz range electric field pulse for just a picosecond, which lead to a 1,000-fold increase in exciton density. An exciton is a… » 12/22/11 8:30am 12/22/11 8:30am
