Encapsulation layers keep carbon nanotube transistors stable in open air

Until now, researchers have also struggled to create a carbon nanotube-based integrated circuit in which the transistors are spatially uniform across the material, which is needed for the overall system to work.

Studying nanoparticles one at a time

Researchers have developed a new way to study nanoparticles one at a time, and have discovered that individual particles that may seem identical in fact can have very different properties. The results may prove to be important when developing new materials or applications such as hydrogen sensors for fuel cell cars.

Researchers use laser to levitate, glowing nanodiamonds in vacuum

Work represents first step towards a levitated system combining optical, spin and mechanical degrees of freedom.

Improved stability of electron spins in qubits

Calculation with electron spins in a quantum computer assumes that the spin states last for a sufficient period of time. Physicists have now demonstrated that electron exchange in quantum dots fundamentally limits the stability of this information.

Carbon nanotubes open new path toward quantum information technologies

The ability to generate single photons on demand holds the key to realization of such a communication scheme. By demonstrating that incorporation of pristine single-walled carbon nanotubes into a silicon dioxide matrix could lead to creation of solitary oxygen dopant state capable of fluctuation-free, room-temperature single photon emission, researchers revealed a new path toward on-demand single photon generation.

Shedding light on the era of Dark silicon

We will soon live in an era where perhaps more than 80 per cent of computer processors' transistors must be powered off and 'remain dark' at any time to prevent the chip from overheating. Researchers are racing against time to find smart solutions to the rapidly advancing era of ?dark silicon?.

Scientists witness and measure displacement of atoms

This research provides immediate insights into lithium-ion battery performance and far-reaching implications for the design of new materials for energy generation and storage, next gen computing, green technologies, and other areas.

Semiconductor quantum dots as ideal single-photon source

With the help of a semiconductor quantum dot, physicists have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream of identical photons.
