Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

UbiQD, the Los Alamos spinout that specializes in cadmium-free quantum dot materials with potential in a variety of optical ...

The researchers deployed a special quantum effect called the two-photon spin-exchange Auger process to produce hot electrons far more efficiently than before. This process allows two low-energy ...

Light excites the quantum dot core, transferring energy to a magnetic manganese ion through ultrafast sub-picosecond spin exchange. The manganese ion then undergoes spin-flip relaxation, resulting ...
