"We’re talking about the use of physics at the nanoscale for a completely new application," says Federico Capasso. © | Image courtesy of Steven J. Byrnes

“The key is in these beautiful circuit diagrams,” says Capasso. The three diode-resistor generator circuits shown have different temperature inputs. A circuit at thermal equilibrium (A) generates no current; (B) is a conventional rectifier circuit. The Harvard team proposes a twist—shown in (C). © | Image courtesy of Federico Capasso and PNAS
