Tiny Graphene Drum for Future Quantum Computer and Sensor Technologies
Scientists from Netherlands' Delft University of Technology have demonstrated that they can detect extremely small changes in position and forces on very small drums of graphene. Graphene drums have great potential to be used as sensors in devices such as mobile phones. Using their unique mechanical properties, these drums could also act as memory chips in a quantum computer. In their experiments, the scientists used microwave-frequency light to 'play' the graphene drums, to listen to its 'nano sound', and to explore the way graphene in these drums moves. They did this by using a 2D crystal membrane as a mirror in an optomechanical cavity.
