Liquid-based photodetector leverages water molecules for quantum dot enhancement, offering high sensitivity and ...

A promising route for quantum dot solar cells is a semiconductor ink with the goal of enabling the coating of large areas of solar cell substrates in a single deposition step and thereby eliminating ...

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 ...

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 ...

Graphene — a single layer of carbon atoms arranged in a honeycomb lattice — is already attracting interest for its various applications in electronics and optoelectronics, including its use as ...

This allows quantum computers to solve problems that would take regular computers years or even centuries to crack. But ...
