Dimerization-Induced Fermi-Surface Reconstruction in IrTe2
Man Jin Eom, Kyoo Kim, Y. J. Jo +6
We report a de Haas-van Alphen (dHvA) oscillation study on IrTe2 single crystals showing complex dimer formations. By comparing the angle dependence of dHvA oscillations with band…
Transforming a Surface State of Topological Insulator by a Bi Capping Layer
Han Woong Yeom, Sung Hwan Kim, Woo Jong Shin +7
We introduce a dinstint approach to engineer a topologically protected surface state of a topological insulator. By covering the surface of a topological insulator, Bi2Te2Se, with…
Persistent Topological Surface State at the Interface of Bi2Se3 Film Grown on Patterned Graphene
Namdong Kim, Paengro Lee, Youngwook Kim +6
We employed graphene as a patternable template to protect the intrinsic surface states of thin films of topological insulators (TIs) from environment. Here we find that the graphen…
Orbital-driven nematicity in FeSe
S. -H. Baek, D. V. Efremov, J. M. Ok +3
A very fundamental and unconventional characteristic of superconductivity in iron-based materials is that it occurs in the vicinity of {\it two} other instabilities. Apart from a t…
Controlling the 2DEG states evolution at a metal/BiSe interface
Han-Jin Noh, Jinwon Jeong, En-Jin Cho +5
We have demonstrated that the evolution of the two-dimensional electron gas (2DEG) system at an interface of metal and the model topological insulator (TI) BiSe can be cont…
Edge and Interfacial States in a 2D Topological Insulator:Bi(111) Bilayer on BiTeSe
Sung Hwan Kim, Kyung-Hwan Jin, Joonbum Park +4
The electronic states of a single Bi(111) bilayer and its edges, suggested as a two dimensional topological insulator, are investigated by scanning tunneling spectroscopy (STS) and…
