Core/shell quantum dots represent a class of semiconductor nanocrystals in which a core material is overcoated by a shell of a wider-band-gap semiconductor. This heterostructuring serves to passivate ...

Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers ...

Quantum dots and quantum wells represent quintessential semiconductor nanostructures in which charge carriers are confined in one or more dimensions at length scales comparable to their de Broglie ...

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 ...
