A new radiation detector made from graphene

Graphene is a remarkable material: light, strong, transparent and electrically conductive. It can also convert heat to electricity, and researchers have recently exploited this thermoelectric property to create a new kind of radiation detector. Classified as a bolometer, the new device has a fast response time and works over a wide range of temperatures. With a simple design and relatively low cost, this device could be scaled up, enabling a wide range of commercial applications. …read more
