What was discovered
In thin films of a chromium-doped topological insulator, a quantised Hall resistance was observed without an external magnetic field. It opened the way to dissipationless conduction in topological electronics.
What it led to
- low-dissipation topological electronics
- chiral edge states for topological quantum computing
