Epitaxial growth of two-dimensional stanene
Fengfeng Zhu,Wei-jiong Chen,Yong Xu,Chunlei Gao,Dandan Guan,Canhua Liu,Dong Qian,Shou-Cheng Zhang,Shou-Cheng Zhang,Jin-Feng Jia +9 more
TL;DR: In this paper, the authors reported the successful fabrication of 2D stanene by molecular beam epitaxy, confirmed by atomic and electronic characterization using scanning tunnelling microscopy and angle-resolved photoemission spectroscopy, in combination with first-principles calculations.

Majorana Zero Mode Detected with Spin Selective Andreev Reflection in the Vortex of a Topological Superconductor
Hao-Hua Sun,Kai-Wen Zhang,Lun-Hui Hu,Chuang Li,Guan-Yong Wang,Hai-Yang Ma,Zhu-An Xu,Chunlei Gao,Dandan Guan,Yaoyi Li,Canhua Liu,Dong H Qian,Yi Cheng Zhou,Liang Fu,Shao-Chun Li,Fu-Chun Zhang,Jin-Feng Jia +16 more
TL;DR: In this paper, a spin-polarized scanning tunneling microscopy or spectroscopy has been applied to probe spin selective Andreev reflection (SSAR) of MZMs in a topological superconductor of the Bi-Te-3/NbSe-2 heterostructure.
Journal ArticleDOI
Experimental detection of a Majorana mode in the core of a magnetic vortex inside a topological insulator-superconductor Bi(2)Te(3)/NbSe(2) heterostructure.
Jin-Peng Xu,Mei Xiao Wang,Zhi-Long Liu,Jian-Feng Ge,Xiaojun Yang,Canhua Liu,Z. A. Xu,Dandan Guan,Chun Lei Gao,Dong Qian,Ying Liu,Qiang Hua Wang,Fu-Chun Zhang,Fu-Chun Zhang,Qi-Kun Xue,Jin-Feng Jia,Jin-Feng Jia +16 more
TL;DR: This work provides self-consistent evidences of Majorana fermions and also suggests a possible route to manipulating them by systematically investigating the spatial profile of the Majorana mode and the bound quasiparticle states within a vortex in Bi(2)Te(3) films grown on a superconductor NbSe(2).
Journal ArticleDOI
Coexistence of the topological state and a two-dimensional electron gas on the surface of Bi(2)Se(3).
Marco Bianchi,Dandan Guan,Dandan Guan,Shining Bao,Jianli Mi,Bo B. Iversen,Philip D. C. King,Philip Hofmann +7 more
TL;DR: It is shown that the single Dirac cone comprising the topological state of the prototypical topological insulator Bi(2)Se(3) can co-exist with a two-dimensional electron gas (2DEG), a cornerstone of conventional electronics.
