Power/Performance Bits: March 4


Photon glue Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials and this effect could harness the most useful characteristics from each material for hybrid solar cells and high efficiency lighting, among other applications. To this end, researchers at the University of Michigan and Queens Coll... » read more
