A superconducting diode without an external magnetic field

Superconductors are the key to lossless current flow. However, the realization of superconducting diodes has only recently become an important topic of fundamental research. An international research team involving the theoretical ...

Researchers move closer to controlling two-dimensional graphene

The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon's current-conducting capabilities via doping, which is a process ...

Janus graphene opens doors to sustainable sodium-ion batteries

In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel ...

Molecular bridges power up printed electronics

The exfoliation of graphite into graphene layers inspired the investigation of thousands of layered materials: amongst them transition metal dichalcogenides (TMDs). These semiconductors can be used to make conductive inks ...

A magnetic twist to graphene

Electrons in materials have a property known as 'spin," which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the ...
