Graphene
Graphene quantum dots (GQDs) are fabricated with minimal oxidation by S. Yoo, Y.-H. Cho, S. Jeon, and co-workers using a graphite intercalation compound method. The GQDs are shown to emit blue light, and these can be incorporated into polymeric host layers as the active layer in a highly effective blue LED device.
Metasurfaces
By merging plasmonic metamaterials with quantum-engineered inter-subband transitions in a semiconductor heterostructure, M. A. Belkin and co-workers have realized a 220-nanometer-thick electrically tunable mirror that can change its reflectivity in less than 10 nanoseconds in response to an applied electrical bias of a few volts, across a broad tunable range.
