This lens is just three atoms thick and works like a quantum lighthouse

A team of physicists collaborating between the University of Amsterdam and Stanford University combined the lighthouse engineering theory and electrostatically bound “excitons” to build the world’s thinnest lens. At 0.6 nanometers thick and half a millimeter wide, the design uses just three atoms of a special material called tungsten disulphide (WS2), whose quantum properties make […]
