Noise signatures for determining chiral Majorana fermion modes

26 Aug 2020 Li Yu-Hang Liu Jie Liu Haiwen Jiang Hua Sun Qing-Feng Xie X. C.

The conductance measurement of a half quantized plateau in a quantum anomalous Hall insulator-superconductor structure is reported by a recent experiment [Q. L. He \textit{et al.}, Science 357, 294-299 (2017)], which suggests the existence of the chiral Majorana fermion modes. However, such half quantized conductance plateau may also originates from a disorder-induced metallic phase... (read more)
