Quantum materials emit light as though it were only a positive pulse, rather than a positive-negative oscillation.
Light Lasers and Optics
Emulating impossible “unipolar” laser pulses paves the way for processing quantum information
Graphene-hBN breakthrough to spur new LEDs, quantum computing
Study uncovers first method for producing high-quality, wafer-scale hexagonal boron nitride.
Most powerful laser in the U.S. to begin operations soon, supported by $18.5M from the NSF
With first light anticipated in 2022, the NSF will provide five years of operations funding, ramping up as the ZEUS user facility progresses to full capacity.
Nanotech OLED electrode liberates 20% more light, could slash display power consumption
A five-nanometer-thick layer of silver and copper outperforms conventional indium tin oxide without adding cost.
“Egg carton” quantum dot array could lead to ultralow power devices
By putting a twist on new “2D” semiconductors, researchers have demonstrated their potential for using single photons to transmit information.
Mapping quantum structures with light to unlock their capabilities
Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors.
