Atom-Thick Graphene Sheets Could Make Great Camera Sensors

Graphene, a one-atom-thick sheet of carbon, could end up making a pretty good camera sensor. Researchers at MIT have discovered that graphene can turn light into electricity, but not the way you’d think.
Unlike camera sensors and solar panels which rely on the photovoltaic effect, graphene creates a current because of a temperature difference. When light [...]
