Argonne scientists have unveiled new methods for controlling material properties. The breakthrough enables researchers to ...

The properties of quantum dots (QDs) are determined by various factors, including size, shape, composition, and structure, such as whether they ... significant efforts were required to improve basic ...

Laser technology is going to play an important role in advancing quantum devices, healthcare tools, and optical computing ...

Quantum dot FP lasers have an ensemble of self-assembled QDs inside the cavity as shown in Fig. 1.By simply modulating the laser's injection current, the laser emits a stream of digital data bits ...

The research team engineered quantum dots that produce red, green, or blue laser light by precisely controlling the particles' composition and structure. When excited by an external light source, ...

Argonne researchers have shown that they can use light to temporarily alter the crystal symmetry within lead sulfide quantum dots. This process reduces the off-centering of lead atoms and affects the ...

A research team led by Professor Sun Qing-Feng in collaboration with Professor He Lin's research group from Beijing Normal ...

Associate Professor Jia said the researchers achieved this by fine-tuning the structure of the quantum dots at an atomic level, reducing defects that can interfere with light emission.

However, newly published research from the University of Oklahoma proves that adding a covering to one of these light sources, called a colloidal quantum dot, can cause them to shine without ...
