Anomalous quantization trajectory and parity anomaly in Co cluster decorated BiSbTeSe2 nanodevices

Anomalous quantization trajectory and parity anomaly in Co cluster decorated BiSbTeSe2 nanodevices

The topological surface states usually appear in pairs in a topological insulator, with one on the top surface and the other on the bottom surface. Here, Zhang et al. utilize Co cluster to induce a Zeeman gap on one surface through antiferromagnetic exchange coupling, and observe a quasi-half-intege...
