Quantum dots articles from across Nature Portfolio

Graphene quantum dots promise applications for spin and valley qubits; however a demonstration of phase coherent oscillations has been lacking. Here the authors report coherent charge oscillations and measurements of coherence times in highly tuneable double quantum dots in bilayer graphene.

The authors demonstrate a large ensemble of quantum dots which is characterized using a cryogenic multiplexer-demultiplexer circuit based on selective area growth nanowires, establishing the feasibility of scaling future quantum circuits.

Colloidal quantum dots remain unexplored for applications in single-electron devices. Here, the authors demonstrate single-electron transistors using single PbS colloidal quantum dot, highlighting their room-temperature operation.

Time-resolved measurements show that coupling between electrons and phonons in lead halide perovskites can mediate attractive interactions between excitons, although the interaction strength depends on the specific material.

Interactions between a localized magnetic moment and electrons in a metal can produce an emergent resonance that affects the metal’s properties. A realization of this Kondo effect in MoS₂ provides an opportunity to study it in microscopic detail.

Phase transition dynamics are an important concern in the wide applications of metal halide perovskites. Here authors apply low-dose imaging technique to reveal the phase transition dynamics of CsPbI₃ during in-situ heating process with atomic resolution.

An article in Angewandte Chemie International Edition resurfaces metal halide perovskite nanocrystals with a reactive, liquid ligand to produce efficient and stable red perovskite light-emitting diodes.

An article in Nature Materials shows that a ‘quantum dot molecule’ — two fused and electronically coupled quantum dots — can easily switch between two distinct emission colours when induced by an electric field.

An article in the Journal of the American Chemical Society decorates type-I CdS-ZnS core–shell quantum dots with metallic domains to activate them as hydrogen evolution photocatalysts.

An article in Science uses photogenerated nitrene radicals to non-specifically bond together colloidal inorganic nanocrystals as they are 3D printed into robust functional structures.

An article in Nature Communications uses an artificial-intelligence-guided robot to accelerate the discovery and fabrication of chiroptically active films.
