Giant negative magnetoresistance induced by the chiral anomaly in individual Cd3As2 nanowires
Cai-Zhen Li, Li-Xian Wang, Haiwen Liu +3
Cd3As2 is a newly booming Dirac semimetal with linear dispersion along all three momentum directions and can be viewed as 3D analog of graphene. As breaking of either time reversal…
Electrical Probing of Field-Driven Cascading Quantized Transitions of Skyrmion Cluster States in MnSi Nanowires
Haifeng Du, Dong Liang, Chiming Jin +11
Magnetic skyrmions are topologically stable whirlpool-like spin textures that offer great promise as information carriers for future ultra-dense memory and logic devices1-4. To ena…
Transport Properties of Topological Insulators Films and Nanowires
Yi Liu, Zheng Ma, Yanfei Zhao +2
The last several years have witnessed the rapid developments in the study and understanding of topological insulators. In this review, after a brief summary of the history of topol…
Superconductivity in single crystalline Pb nanowires contacted by normal metal electrodes
Jian Wang, Yi Sun, Mingliang Tian +3
The transport properties of superconducting single crystal Pb nanowires of 55 nm and 70 nm diameter are studied by standard four electrodes method. Resistance-temperature (R-T) sca…
Observation of the superconducting proximity effect and possible evidence for Pearl vortices in a candidate topological insulator
Duming Zhang, Jian Wang, Ashley M. DaSilva +5
We report the observation of the superconducting proximity effect in nanoribbons of a candidate topological insulator (Bi2Se3) which is interfaced with superconducting (tungsten) c…
Evidence for electron-electron interaction in topological insulator thin films
Jian Wang, Ashley M. DaSilva, Cui-Zu Chang +6
We consider in our work high quality single crystal thin films of Bi2Se3, grown by molecular beam epitaxy, both with and without Pb doping. Our ARPES data demonstrate topological s…
Superconductivity and quantum oscillations in crystalline Bi nanowires
Mingliang Tian, Jian Wang, Qi Zhang +3
While bulk bismuth (Bi) is a semimetal, we have found clear evidence of superconductivity in a crystalline 72 nm diameter Bi nanowire below 1.3 K. In a parallel magnetic field (H),…
Unusual giant magnetoresistance effect in heterojunction structure of ultra-thin single-crystal Pb film on silicon substrate
Jian Wang, Xu-Cun Ma, Yun Qi +7
Superconductor films on semiconductor substrates draw much attention recently since the derived superconductor-based electronics have been shown promising for future data process a…
