Next-generation nanoengineered switches can cut heat loss in electronics tagged posts

Electronic devices lose energy as heat due to the movement of electrons. Now, a breakthrough in nanoengineering has produced a new kind of switch that matches the performance of the best traditional designs while pushing beyond the power-consumption limits of modern electronics.

Researchers from the University of Michigan have achieved what scientists have been trying to execute for a long time: designing electronics that harness excitons—pairs of an electron and a corresponding hole (a missing electron) bound together forming a charge-neutral particle—instead of electrons.

The newly designed nanoengineer...
