Quantum dots have spent two decades in the spotlight as tiny semiconductor crystals whose colors can be dialed in simply by ...

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these ...

In one sentence: A quantum dot laser is a semiconductor laser whose gain medium contains nanoscale quantum dots that confine electrons and holes in all three dimensions, producing discrete energy ...

Quantum dots (QDs) are semiconducting nanoparticles with distinct optical and electrical properties that fall between bulk materials and discrete molecules. QDs' size-dependent tunability makes them ...

Determining the entropy of a system typically entails measuring its heat capacity. That approach is harder to apply when the system consists of a very small number of electrons corralled in a tiny ...

Quantum dots are nanoscale semiconductor or carbon-based particles that exhibit size-tunable optical and electronic properties through quantum confinement. Advances in controlled synthesis have ...

Engineers at the University of Wisconsin–Madison have designed a new type of quantum nanostructure that could enable optical ...
