Single Photon Light Emitting Diodes

LED features single photon emission article tells that Graphene Flagship is hitting its research out of the proverbial park by demonstrating an all-electrical quantum LED with single-photon emission. The LEDs are atomically thin and have potential as on-chip photon sources that can be used in quantum information apps. Graphene Flagship researchers used layers that included transition
