Landau quantization and the thickness limit of topological insulator thin films of Sb2Te3
Yeping Jiang, Yilin Wang, Mu Chen +7
We report the experimental observation of Landau quantization of molecular beam epitaxy grown Sb2Te3 thin films by a low-temperature scanning tunneling microscope. Different from a…
Fermi Level Tuning of Epitaxial Sb2Te3 Thin Films on Graphene by Regulating Intrinsic Defects and Substrate Transfer Doping
Yeping Jiang, Y. Y. Sun, Mu Chen +9
High-quality Sb2Te3 films are obtained by molecular beam epitaxy on graphene substrate and investigated by in situ scanning tunneling microscopy/spectroscopy. Intrinsic defects res…
Anisotropic vortex lattice structures in the FeSe superconductor
Hsiang-Hsuan Hung, Can-Li Song, Xi Chen +3
In the recent work by Song et al. [Science 332, 1410 (2011)], the scanning tunneling spectroscopy experiment in the stoichiometric FeSe reveals evidence for nodal superconductivity…
Current induced anisotropic magnetoresistance in topological insulator films
Jian Wang, Handong Li, Cui-Zu Chang +7
Topological insulators are insulating in the bulk but possess spin-momentum locked metallic surface states protected by time-reversal symmetry. The existence of these surface state…
Phase Separation and Magnetic Order in K-doped Iron Selenide Superconductor
Wei Li, Hao Ding, Peng Deng +8
Alkali-doped iron selenide is the latest member of high Tc superconductor family, and its peculiar characters have immediately attracted extensive attention. We prepared high-quali…
Band structure engineering in (Bi1-xSbx)2Te3 ternary topological insulators
Jinsong Zhang, Cui-Zu Chang, Zuocheng Zhang +10
Three-dimensional (3D) topological insulators (TI) are novel quantum materials with insulating bulk and topologically protected metallic surfaces with Dirac-like band structure. Th…
Power-Law Decay of Standing Waves on the Surface of Topological Insulators
Jing Wang, Wei Li, Peng Cheng +9
We propose a general theory on the standing waves (quasiparticle interference pattern) caused by the scattering of surface states off step edges in topological insulators, in which…
Crossover between weak localization and weak antilocalization in magnetically doped topological insulator
Minhao Liu Jinsong Zhang, Cui-Zu Chang, Zuocheng Zhang +10
Topological insulators (TI) are a new class of quantum materials with insulating bulk enclosed by topologically protected metallic boundaries. The surface states of three-dimension…
