Physicists measured how readily a current of electron pairs flows through 'magic-angle' graphene, a major step toward understanding how this unusual material superconducts. By determining how readily ...

This time, the scientists placed graphene quantum dots into a controlled environment. These graphene dots are nanoscale materials made by arranging a single layer of graphene—which, like ...

By twisting layers of graphene, researchers discovered a unique electronic crystal where electrons freeze in place yet allow ...

Liquid-based photodetector leverages water molecules for quantum dot enhancement, offering high sensitivity and wavelength-specific customization for optical and medical applications.

"Magnetic graphene nanoribbons -- narrow strips of graphene formed by fused benzene rings -- offers tremendous potential for quantum technologies due to their long spin coherence times and the ...

Quantum dots – nanoparticles of semiconductors – were first theorized in the 1970s and then successfully synthesized in the early 1980s. When semiconductor particles are made small enough, they ...

"Magnetic graphene nanoribbons—narrow strips of graphene formed by fused benzene rings—offer tremendous potential for quantum technologies due to their long spin coherence times and the ...

The Manchester team used electron-beam lithography and isotropic dry etching to make the quantum dot, the leads and the gate electrodes — all from the same sheet of graphene. Just as the current ...

Behind them is the scanning tunneling microscope (STM) they use to create and study graphene quantum dots.

Quantum dots are crystals of a fluorescent semiconductor material with a diameter of as few as 10 to 100 atoms (2-10 nm). They are used as labels for imaging molecules because of their very narrow ...
