By all measures, graphene should not exist. The fact it does comes down to some neat loophole in physics which sees with an impossible 2D sheet of atoms behave like a good 3D material. New research has delved into graphene’s rippling, discovering a physical happening on an atomic scale which

Graphene can be used to enhance photonics, as a detector for light, an optoelectronic transceiver, or as part of high-resolution imaging systems. A surprising application of graphene is its use in photodetectors. Light detection capabilities of graphene are inherently limited because a single sheet of the material absorbs only ~2.3%
