Composition-spread Growth and the Robust Topological Surface State of Kondo insulator SmB6 Thin Films
Jie Yong, Yeping Jiang, Demet Usanmaz +7
Topological insulators are a class of materials with insulating bulk but protected conducting surfaces due to the combination of spin-orbit interactions and time-reversal symmetry.…
Mass acquisition of Dirac fermions in Cr-doped topological insulator Sb2Te3 films
Yeping Jiang, Zhi Li, Canli Song +7
We introduce time-reversal-symmetry breaking by doping Cr atoms into the topmost quintuple layer or into the bulk of Sb2Te3 thin films. We find that even at a high Cr-doping level…
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…
