Symmetric graphene quantum dots for future qubits

Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists at Forschungszentrum Jülich and RWTH Aachen University ...

2D boundaries could create electricity

There's still plenty of room at the bottom to generate piezoelectricity. Engineers at Rice University and their colleagues are showing the way.

Researchers create flow-driven rotors at the nanoscale

Researchers from TU Delft have constructed the smallest flow-driven motors in the world. Inspired by iconic Dutch windmills and biological motor proteins, they created a self-configuring, flow-driven rotor from DNA that converts ...

Light-emitting electrochemical cells for recyclable lighting

A low-cost and easy-to-manufacture lighting technology can be made with light-emitting electrochemical cells. Such cells are thin-film electronic and ionic devices that generate light after a low voltage is applied. Researchers ...

A material keyboard made of graphene

Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the ...

Counting single photons at unprecedented rates

In high-end 21st century communications, information travels in the form of a stream of light pulses typically traveling through fiber optic cables. Each pulse can be as faint as a single photon, the smallest possible unit ...
