Want your com­puter to go faster? Add light!

Sci­en­tists, including one of Indian-​​origin, have devel­oped novel devices that could usher in a new wave of highly effi­cient elec­tronics, including com­puters, that can be turned on and off using light. Every second, your com­puter must process bil­lions of com­pu­ta­tional steps to pro­duce even the sim­plest out­puts. Imagine if every one of those steps could be made just a tiny bit more effi­cient, researchers said.
“It would save pre­cious nanosec­onds,” said North­eastern Uni­ver­sity Boston, assis­tant pro­fessor of physics Swastik Kar. Kar and his col­league Yung Joon Jung, have devel­oped a series of novel devices that do just that. The duo com­bined their exper­tise – Kar’s in graphene, a carbon-​​based mate­rial known for its strength and con­duc­tivity, and Jung’s in the mechanics of carbon nan­otubes, which are nanometre-​​sized rolled up sheets of graphene to unearth a phys­ical phe­nom­enon that could usher in a new wave of highly effi­cient electronics.
