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…
Structural versus electronic distortions of symmetry-broken IrTe
Hyo Sung Kim, Tae-Hwan Kim, Junjie Yang +2
We investigate atomic and electronic structures of the intriguing low temperature phase of IrTe2 using high-resolution scanning tunneling microscopy and spectroscopy. We confirm va…
Atomic scale variation of electron tunneling into a Luttinger liquid ? : High resolution scanning tunneling spectroscopy study on Au/Ge(001)
Jewook Park, Kan Nakatsuji, Tae-Hwan Kim +3
Au-induced atomic wires on the Ge(001) surface were recently claimed to be an ideal 1D metal and their tunneling spectra were analyzed as the manifestation of a Tomonaga-Luttinger…
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…
