Conductance Quantization in PbTe Nanowires
Wenyu Song, Yuhao Wang, Wentao Miao +17
PbTe nanowires coupled to a superconductor have recently been proposed as a potential Majorana platform. The hallmark of the one-dimensional nature of ballistic nanowires is their…
Quantized anomalous Hall resistivity achieved in molecular beam epitaxy-grown MnBi2Te4 thin films
Yunhe Bai, Yuanzhao Li, Jianli Luan +17
The intrinsic magnetic topological insulator MnBi2Te4 provides a feasible pathway to high temperature quantum anomalous Hall (QAH) effect as well as various novel topological quant…
Selective Trapping of Hexagonally Warped Topological Surface States in a Triangular Quantum Corral
Mu Chen, Yeping Jiang, Junping Peng +10
The surface of a three-dimensional topological insulator (TI) hosts two-dimensional massless Dirac fermions (DFs), the gapless and spin-helical nature of which yields many exotic p…
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…
