New Synapse-like Phototransistor

 Ground- and excited-state charge transfer in bilayer NC/SWCNT heterojunctions.

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a breakthrough in energy-efficient phototransistors. Such devices could eventually help computers process visual information more like the human brain and be used as sensors in things like self-driving vehicles.

The structures rely on a new type of semiconductor — metal-halide perovskites — which have proven to be highly efficient at converting sunlight into electrical energy and shown tremendous promise in a range of other technologies.

“In general, these perovskite semiconductors are a really unique functional system with potential benefits for a number of different technologies,” said Jeffrey Blackb...
