Observation of Aharonov-Bohm effect in PbTe nanowire networks
Zuhan Geng, Zitong Zhang, Fangting Chen +19
We report phase coherent electron transport in PbTe nanowire networks with a loop geometry. Magneto-conductance shows Aharonov-Bohm (AB) oscillations with periods of and $h/2…
Ambi-chiral anomalous Hall effect in magnetically doped topological insulators
Chang Liu, Yunyi Zang, Yan Gong +4
The chirality associated with broken time reversal symmetry in magnetically doped topological insulators has important implications to the quantum transport phenomena. Here we repo…
Selective area epitaxy of PbTe-Pb hybrid nanowires on a lattice-matched substrate
Yuying Jiang, Shuai Yang, Lin Li +17
Topological quantum computing is based on braiding of Majorana zero modes encoding topological qubits. A promising candidate platform for Majorana zero modes is semiconductor-super…
Incommensurate smectic phase in close proximity to the high-Tc superconductor FeSe/SrTiO3
Yonghao Yuan, Xuemin Fan, Xintong Wang +4
Superconductivity is significantly enhanced in monolayer FeSe grown on SrTiO3, but not for multilayer films, in which large strength of nematicity develops. However, the link betwe…
Distinct quantum anomalous Hall ground states induced by magnetic disorders
Chang Liu, Yunbo Ou, Yang Feng +8
The quantum anomalous Hall (QAH) effect in magnetic topological insulator (TI) represents a new state of matter originated from the interplay between topology and magnetism. The de…
Gate Tunable Supercurrent in Josephson Junctions Based on Bi2Te3 Topological Insulator Thin Films
Wei-Xiong Wu, Yang Feng, Yun-He Bai +13
We report transport measurements on Josephson junctions consisting of Bi2Te3 topological insulator (TI) thin films contacted by superconducting Nb electrodes. For a device with jun…
