Electrically Driven Quantum Dot Lasers, a Fundamental Nanomaterials/Nanophotonics Approach (E-QUAL) Ghent University
For 20 years, colloidal quantum dots (QDs) have been seen as a most promising optical gain material, offering tunable characteristics and a suitability for solution-based processing. However, while the formation of optically pumped QD lasers has become common practice, electrically pumped QD lasers remain to be demonstrated. To make optical gain overcome optical losses at reasonable threshold currents, better QDs and low-loss QD cavities are ...
