Emergence of Nearly Flat Bands through an Embedded Kagome Lattice in an Epitaxial Two-dimensional Ge Layer on ZrB2(0001)
Antoine Fleurence, Chi-Cheng Lee, Rainer Friedlein +8
Ge atoms segregating on zirconium diboride thin films grown on Ge(111) were found to crystallize into a two-dimensional bitriangular structure which was recently predicted to be a…
Temperature-driven modification of surface electronic structure on bismuth, a topological border material
Y. Ohtsubo, Y. Yamashita, J. Kishi +7
Single crystalline bismuth (Bi) is known to have a peculiar electronic structure which is very close to the topological phase transition. The modification of the surface states of…
Spin-polarized quasi 1D state with finite bandgap on the Bi/InSb(001) surface
J. Kishi, Y. Ohtsubo, T. Nakamura +13
One-dimensional (1D) electronic states were discovered on 1D surface atomic structure of Bi fabricated on semiconductor InSb(001) substrates by angle-resolved photoelectron spectro…
Surface Tomonaga-Luttinger liquid state on Bi/InSb(001)
Yoshiyuki Ohtsubo, Jun-ichiro Kishi, Kenta Hagiwara +8
A 1D metallic surface state was created on an anisotropic InSb(001) surface covered with Bi. Angle-resolved photoelectron spectroscopy (ARPES) showed a 1D Fermi contour with almost…
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…
Nitrogen-Functionalized Graphene Nanoflakes (GNFs:N): Tunable Photoluminescence and Electronic Structures
J. W. Chiou, Sekhar C. Ray, S. I. Peng +22
This study investigates the strong photoluminescence (PL) and X-ray excited optical luminescence observed in nitrogen-functionalized 2D graphene nanoflakes (GNFs:N), which arise fr…
Hybridized electronic states in potassium-doped picene probed by soft x-ray spectroscopies
Hiroyuki Yamane, Nobuhiro Kosugi
The electronic structure of the unoccupied and occupied states of potassium (K)-doped and undoped picene crystalline films has been investigated by using the element-selective and…
