Strong surface termination dependence of the electronic structure of polar superconductor LaFeAsO revealed by nano-ARPES
Sung Won Jung, Luke C. Rhodes, Matthew D. Watson +7
The electronic structures of the iron-based superconductors have been intensively studied by using angleresolved photoemission spectroscopy (ARPES). A considerable amount of resear…
Fermiology and electron-phonon coupling in the 2H and 3R polytypes of NbS
Zakariae El Youbi, Sung Won Jung, Christine Richter +3
We investigate the electronic structure of the 2H and 3R polytypes of NbS. The Fermi surfaces measured by angle-resolved photoemission spectroscopy show a remarkable difference…
Spectral functions of CVD grown MoS monolayers after chemical transfer onto Au surface
Sung Won Jung, Sangyeon Pak, Sanghyo Lee +9
The recent rise of van der Waals (vdW) crystals has opened new prospects for studying versatile and exotic fundamental physics with future device applications such as twistronics.…
Bulk and surface electronic states in the dosed semimetallic HfTe
Zakariae El Youbi, Sung Won Jung, Saumya Mukherjee +8
The dosing of layered materials with alkali metals has become a commonly used strategy in ARPES experiments. However, precisely what occurs under such conditions, both structurally…
Fermi-crossing Type-II Dirac fermions and topological surface states in NiTe2
Saumya Mukherjee, Sung Won Jung, Sophie F. Weber +9
Transition-metal dichalcogenides (TMDs) offer an ideal platform to experimentally realize Dirac fermions. However, typically these exotic quasiparticles are located far away from t…
Holstein polaron in a valley-degenerate two-dimensional semiconductor
Mingu Kang, Sung Won Jung, Woo Jong Shin +5
Two-dimensional (2D) crystals have emerged as a class of materials with tuneable carrier density. Carrier doping to 2D semiconductors can be used to modulate manybody interactions…
Universal Mechanism of Band-Gap Engineering in Transition-Metal Dichalcogenides
Mingu Kang, Beomyoung Kim, Sae Hee Ryu +7
Two-dimensional (2D) van-der-Waals semiconductors have emerged as a class of materials with promising device characteristics owing to the intrinsic bandgap. For realistic applicati…
Two-Dimensional Dirac Fermions Protected by Space-Time Inversion Symmetry in Black Phosphorus
Jimin Kim, Seung Su Baik, Sung Won Jung +5
We report the realization of novel symmetry-protected Dirac fermions in a surface-doped two-dimensional (2D) semiconductor, black phosphorus. The widely tunable band gap of black p…
Self-Assembled Nanowires with Giant Rashba-Type Band Splitting
Jewook Park, Sung Won Jung, Min-Cherl Jung +3
We investigated Pt-induced nanowires on the Si(110) surface using scanning tunneling microscopy (STM) and angle-resolved photoemission (ARP). High resolution STM images show a well…
