A special type of diode made from a crystalline material whose layers are just three atoms thick has been successfully realized for the first time. The superior properties of such ultra-thin crystals ...

Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team has ...

The proof-of-concept uses a van der Waals heterostructure with 2D materials: NbSe 2 – Nb 3 Br 8 – NbSe 2, and is superconducting on one direction, and normally-conducting in the other. Compared with ...
