All-optical transistor

opticaltransistor

Optical computing — using light rather than electricity to perform calculations — could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations exponentially faster than classical computers. An optical switch that can be turned on by a single photon could point toward new designs for both classical and quantum computers.

Graphene Provides Cooling for Electronics

producing semiconductors from graphene

A new discovery shows that graphene provides efficient electronics cooling, reducing the working temperature in hotspots inside a processor by up to 25 percent.

An international group of researchers, headed by Chalmers University of Technology in Sweden, are the first in the world to show that graphene has a heat dissipating effect on silicon based electronics. Continue reading “Graphene Provides Cooling for Electronics” »
