Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical "hotspot" of a ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

This method recovered 85% of the original quantum dots, which still performed almost as well as new ones. The recycled dots were then used to make lasers that worked just like the originals. The team ...

A research team has developed a new technique to rapidly and accurately determine the charge state of electrons confined in semiconductor quantum dots -- fundamental components of quantum computing ...

In what may be one of the first medical uses of nanotechnology, a chemist and a doctor who specializes in infectious childhood diseases have joined forces to create an early detection method for a ...

Recycling method The idea to recycle these particles came up during a team discussion about the high cost of wasted quantum dots. Dillon Downie, a Ph.D. student in the Institute of Photonics at the ...
