Anisotropic transport of Josephson vortices in atomic-layer superconductors on vicinal surfaces
Wenxuan Qian, Yash Chauhan, Ryohei Nemoto +3
Atomic steps have strong influences on surface two-dimensional superconductors. Josephson vortices formed at the atomic steps under magnetic fields may dominate transport phenomena…
Topological surface states hybridized with bulk states of Bi-doped PbSb2Te4 revealed in quasiparticle interference
Yuya Hattori, Keisuke Sagisaka, Shunsuke Yoshizawa +2
Topological surface states of Bi-doped PbSb2Te4 [Pb(Bi0.20Sb0.80)2Te4] are investigated through analyses of quasiparticle interference (QPI) patterns observed by scanning tunneling…
Experimental verification of band convergence in Sr and Na codoped PbTe
Yuya Hattori, Shunsuke Yoshizawa, Keisuke Sagisaka +5
Scanning tunneling microscopy and transport measurements have been performed to investigate the electronic structure and its temperature dependence in heavily Sr and Na codoped PbT…
Visualization of alternating triangular domains of charge density waves in 2H-NbSe by scanning tunneling microscopy
Shunsuke Yoshizawa, Keisuke Sagisaka, Hideaki Sakata
The charge density wave (CDW) state of 2H-NbSe features commensurate domains separated by domain boundaries accompanied by phase slips known as discommensurations. We have unam…
Non-charge-transfer origin of Tc Enhancement in a Surface Superconductor Si(111)-(root7xroot3)-In with Adsorbed Organic Molecules
Kenta Yokota, Shunsuke Inagaki, Wenxuan Qian +5
The effects of adsorption of Zn-phthalocyanine (ZnPc) molecules on the superconductivity of the Si(111)-(root7xroot3)-In surface are studied through transport measurements under ul…
Field resilient superconductivity in atomic layer crystalline materials
Yoichi Higashi, Shunsuke Yoshizawa, Takashi Yanagisawa +3
A recent study [S. Yoshizawa {\it et al}., Nature Communications {\bf 12}, 1462 (2021)] reported the occurrence of field-resilient superconductivity, that is, enhancement of the in…
