(PhysOrg.com) -- In optical devices designed and used to collect light, there has always been a loss of light due to reflection, now, new research by a team of physicists from Spain and England has found, via calculation, that if charged graphene disks of just the right size were made and placed the right distance from one another, they should be able to achieve 100% light absorption. On the team were Sukosin Thongrattanasiri and Javier García de Abajo from Spain and Frank Koppens from the UK. Together they have published a paper in Physical Review Letters describing their research.
