The 2023 Nobel Prize in Chemistry has been awarded to Alexei Ekimov, Louis Brus, and Moungi Bawendi .
They awarded for their work on quantum dots.
Quantum dots are very small crystals with peculiar properties.
Quantum dots have application in a variety of fields, from new-age LED screens to quantum computers.
Quantum dots can contribute to flexible electronics, miniscule sensors, slimmer solar cells, and perhaps encrypted quantum communication.
Quantum dots are tiny particles or nanocrystals of a semiconductor material with diameters in the range of 2-10 nanometers.
Quantum dots are made of a variety of semiconductor materials, including cadmium selenide (CdSe), indium arsenide (InAs), and gallium arsenide (GaAs).
Quantum dots are unique in that their emission wavelength can be tuned by simply changing their size.
