Quantum dots are composed of semiconducting materials like cadmium selenide (CdSe) or indium arsenide (InAs) and can be synthesized through various methods. For instance, colloidal synthesis and ...

Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now ...

In nature, tiny crystals known as nanocrystals are formed slowly over many years. Rocks and minerals react with air, water, and carbon dioxide in a process called chemical weathering. These reactions ...

Shortwave infrared light (SWIR) sensors are desirable in a broad range of applications, particularly in the service robotics, automotive, and consumer electronics sectors. Colloidal quantum dots tuned ...

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these ...

Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality.

The 2023 Nobel Prize in Chemistry was focused on quantum dots -- objects so tiny, they're controlled by the strange rules of quantum physics. Quantum dots used in electronics are often toxic, but ...

Colloidal quantum dots are solution-based nanocrystals prized for their unique light-harvesting abilities. They can illuminate, create color, harness solar energy and function as semiconductors. These ...

Some of today's high-end televisions contain quantum dots, tiny components that can help screens produce more vibrant colors. At least, that's what TV manufacturers claim. If you don't observe the ...
