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…
Impurity-mediated early condensation of an atomic layer electronic crystal
Han Woong Yeom, Deok Mahn Oh, S. Wippermann +1
While impurity has been known widely to affect phase transitions, the atomistic mechanisms have rarely been disclosed. We directly show in atomic scale how impurity atoms induces t…
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…
