Researchers from the Harvard School of Engineering and Applied Sciences (SEAS) have made a breakthrough on a novel single-layer design for building quantum-dot light-emitting devices (QD-LEDs) by stacking quantum dots within an insulating structure having the shape of an egg crate.

The new QD-LED has been claimed to resemble a sandwich with a single active layer of quantum dots nestled in insulation and trapped between two ceramic electrodes and the dots kept apart from each other by the egg-create design.

QD-LEDs can be used in lasers, general light sources, computer screens and televisions. Researchers hoped that the new development will have huge positive repercussions for the technology industry.
