Journal ArticleDOI
Adsorption geometry of tetracene on SiO2/Si (1 1 1) substrate with the balance of molecule–substrate and intermolecular interaction
Hongying Mao,Hongying Mao,Dandan Guan,Meiliang Chen,Weidong Dou,Fei Song,Hanjie Zhang,Haiyang Li,Pimo He,Shining Bao +9 more
TL;DR: In this article, the growth of tetracene on SiO 2 /Si(1.1) substrate has been studied by ultraviolet photo-emission spectroscopy measurements, and the changes in binding energy and work function during the deposition of tetrasene molecules on the substrate indicate an interaction between tetracenes and substrate.
Journal ArticleDOI
Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
Anna Stróżecka,Asier Eiguren,Asier Eiguren,Marco Bianchi,Dandan Guan,C. H. Voetmann,Shining Bao,Ph. Hofmann,Jose Ignacio Pascual,Jose Ignacio Pascual +9 more
TL;DR: In this paper, the spin polarization of the surface bands of Sb(110) was determined using spin-resolved density functional theory calculations, and the existence of the unconventional spin texture was corroborated by the investigations of the electron scattering on this surface.
Journal ArticleDOI
Coupling of superconductivity and Coulomb blockade in Sn nanoparticles.
Jin Qin,Chenxiao Zhao,Bing Xia,Zerui Wang,Yu Liu,Dandan Guan,Shiyong Wang,Yaoyi Li,Hao Zheng,Canhua Liu,Jin-Feng Jia +10 more
TL;DR: The superconducting energy gap can be deduced from the coupling tunneling spectrum and shell effect is observed, and the method to deduce thesuperconducting gap is more simple and precise than that obtained by theoretical fitting.
Journal ArticleDOI
Metastable Face-Centered Cubic Structure and Structural Transition of Sn on 2H-NbSe 2 (0001)
Ai-Min Li,Lu-Dong,Xin-Yi Yang,Zhen Zhu,Guan-Yong Wang,Dandan Guan,Hao Zheng,Yaoyi Li,Canhua Liu,Dong Qian,Jin-Feng Jia +10 more
TL;DR: In this article, the surface structures and properties of Sn islands grown on superconducting substrate 2H-NbSe2(0001) are studied using low temperature scanning tunneling microscopy or spectroscopy.
Journal ArticleDOI
Observation of Magnetism-Induced Topological Edge State in Antiferromagnetic Topological Insulator MnBi4Te7.
Hao-Ke Xu,Mingqiang Gu,Fucong Fei,Yilun Gu,Da Liu,Qiaolin Yu,Shangjie Xue,Xu-Hui Ning,Bo Chen,Hangkai Xie,Zhen Zhu,Dandan Guan,Shiyong Wang,Yaoyi Li,Canhua Liu,Qihang Liu,Fengqi Song,Hao Zheng,Jinfeng Jia +18 more
TL;DR: In this paper , an axion insulator theory was proposed to explain the topological nature of the observed edge states of a magnetism-induced edge state in a topological topological insulator, which is composed of an alternatively stacked magnetic layer and a nonmagnetic layer.
