Researchers at the University of Delaware have invented a technology that is meant to improve the communication between photonics devices. This new innovation could benefit smartphones, laptops, and various other consumer electronics.
silicon-graphene devices capable of transmitting radio-frequency waves at less than a picosecond at a sub-terahertz bandwidth have been successfully created. Silicon has long been a popular material for use in semiconductors found in many electronic devices. Unfortunately, there is a limit to what silicon can do in a semiconductor, due to its carrier mobility. This means that the speed a charge moves through the material, and its indirect bandgap, can dramatically limit the material’s ability to absorb and release light. But scientists believe they’ve found a solution to this problem, in the form of graphene.
