Researchers achieve quantum confinement without shrinking materials by engineering a COF with confined excitons, enabling strong photoluminescence and nerve agent detection. (Nanowerk News) Quantum ...

In quantum technologies, emitter coherence time is a critical bottleneck. Traditional subradiant states—long-lived entangled states in waveguide QED—suppress collective decay through interference but ...

Germanium nanocrystals and quantum dots have emerged as pivotal components in modern semiconductor applications, owing to their unique quantum confinement effects and tunable optoelectronic properties ...

Nanotechnology has significantly reshaped modern science. Now, researchers can manipulate matter at atomic and molecular scales. Among the many forms of nanomaterials, zero-dimensional nanomaterials ...

What are Graphene Quantum Dots? Graphene quantum dots (GQDs) are nanoscale fragments of graphene with lateral dimensions typically below 100 nanometers. These tiny nanostructures exhibit unique ...

Quantum confinement is a physical effect that occurs when the size of a material—usually a semiconductor or conductor—is reduced to the nanoscale thereby restricting the movement of electrons or holes ...
