Journal ArticleDOI
Two-dimensional superconductivity at the interface of a Bi2Te3/FeTe heterostructure
Qing Lin He,Hongchao Liu,Mingquan He,Ying Hoi Lai,Hongtao He,Gan Wang,Kam Tuen Law,Rolf Lortz,Jiannong Wang,Iam Keong Sou +9 more
TL;DR: Transport measurements on a Bi2Te3/FeTe heterostructure fabricated via van der Waals epitaxy demonstrate superconductivity at the interface, which is induced by the Bi2 Te3 epilayer with thickness even down to one quintuple layer, though there is no clear-cut evidence that the observedsuperconductivity isinduced by the topological surface states.
Journal ArticleDOI
Strong correlations, strong coupling, and s -wave superconductivity in hole-doped BaFe 2 As 2 single crystals
Frédéric Hardy,Anna E. Böhmer,L. de' Medici,Massimo Capone,Gianluca Giovannetti,Robert Eder,Lixin Wang,Mingquan He,T. Wolf,Peter Schweiss,Rolf Heid,Alexander Herbig,Peter Adelmann,R. A. Fisher,Christoph Meingast +14 more
TL;DR: In this paper, a comprehensive study of the low-temperature heat capacity and thermal expansion of single crystals of the hole-doped BaFe series was presented, revealing a strong enhancement of electron correlations and the possible proximity of these materials to a Mott insulator.
Journal ArticleDOI
Superconductivity in bundles of double-wall carbon nanotubes.
Wu Shi,Zhe Wang,Qiucen Zhang,Qiucen Zhang,Yuan Zheng,Chao Ieong,Mingquan He,Rolf Lortz,Yuan Cai,Ning Wang,Ting Zhang,Haijing Zhang,Zikang Tang,Ping Sheng,Hiroyuki Muramatsu,Yoong Ahm Kim,Morinobu Endo,Paulo T. Araujo,Mildred S. Dresselhaus +18 more
TL;DR: In this paper, the authors present electrical and thermal specific heat measurements that show superconductivity in double-wall carbon nanotube (DWCNT) bundles and suggest an intrinsic superconducting transition below 6.8ÅK for one particular sample.
Journal ArticleDOI
"Giant" enhancement of the upper critical field and fluctuations above the bulk Tc in superconducting ultrathin lead nanowire arrays.
Mingquan He,Chi Ho Wong,Pok Lam Tse,Yuan Zheng,Haijing Zhang,Frank Leung Yuk Lam,Ping Sheng,Xijun Hu,Rolf Lortz +8 more
TL;DR: In this paper, ultrathin lead (Pb) nanowires were produced in the 6 nm pores of SBA-15 mesoporous silica substrates by chemical vapor deposition.
Journal ArticleDOI
Dichotomy between in-plane magnetic susceptibility and resistivity anisotropies in extremely strained BaFe 2 As 2
Mingquan He,Liran Wang,Felix Ahn,Frédéric Hardy,Thomas Wolf,Peter Adelmann,Jörg Schmalian,Ilya Eremin,Ilya Eremin,Christoph Meingast +9 more
TL;DR: The authors demonstrate the subdominant roles of pure lattice distortions and/or orbital ordering in BaFe2As2 by characterizing the in-plane magnetic susceptibility anisotropy by utilizing a simple method for applying a large symmetry-breaking strain, based on differential thermal expansion.
