Making equal-size colloidal quantum dots

Quantum dots (QDs) are semiconductor particles only a few nanometers across that, thanks to their small size, exhibit peculiar optical and electronic properties due to quantum mechanics. With existing and foreseen applications ...

New method for the molecular functionalization of surfaces

One vision that is currently driving material scientists is to combine organic molecules (and their diverse functionalities) with the technological possibilities offered by extremely sophisticated semiconductor electronics. ...

How quantum dots can 'talk' to each other

So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range. The optical and electrical properties can be controlled ...

Making the shift from blue to red for better LEDs

A new micro-light-emitting diode (micro-LED) developed at KAUST can efficiently emit pure red light and may help in the quest to develop full-color displays based on just a single semiconductor.
