Article Synopsis
  • The quantum anomalous Hall effect has been achieved in a magnetic topological insulator but requires extremely low temperatures, complicating practical use.
  • Researchers propose using honeycomb structures made of Sn and Ge that can support a large energy gap and a ferromagnetic order achieved through surface functionalization.
  • The estimated Curie temperatures for these lattices are significantly higher than previously used materials, suggesting that the quantum anomalous Hall effect could be realized at or near room temperature.
