No losses: Scientists stuff graphene with light

Physicists from MIPT and Vladimir State University, Russia, have converted light energy into surface waves on graphene with nearly 90% efficiency. They relied on a laser-like energy conversion scheme and collective resonances. ...

Researchers create a mechanically tunable graphene quantum dot

Precisely manipulating individual charge carriers is a cornerstone for single-electron transistors and for electronic devices of the future, including solid-state quantum bits (qubits). Quantum dots (QDs) are at the heart ...

Synthesizing single-crystalline hexagonal graphene quantum dots

A KAIST team has designed a novel strategy for synthesizing single-crystalline graphene quantum dots, which emit stable blue light. The research team confirmed that a display made of their synthesized graphene quantum dots ...

Graphene quantum dots for single electron transistors

Scientists from the Higher School of Economics, Manchester University, the Ulsan National Institute of Science & Technology and the Korea Institute of Science and Technology have developed a novel technology that combines ...

A novel graphene quantum dot structure takes the cake

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within ...

Researchers developing 2-D materials similar to graphene

Chemists are working to synthesize the next generation of super materials for high-performance electronics, solar cells, photodetectors and quantum computers. While they have made progress with compound materials, they have ...
