Metal-induced gap states in epitaxial organic-insulator/metal interfaces
Manabu Kiguchi, Ryotaro Arita, Genki Yoshikawa +8
We have shown, both experimentally and theoretically, that the metal-induced gap states (MIGS) can exist in epitaxially grown organic insulator/metal interfaces. The experiment is…
One-dimensional ordered structure of a-sexithienyl on Cu(110)
Manabu Kiguchi, Shiro Entani, Genki Yoshikawa +1
We have studied atomic structures of a-sexithienyl (6T) films grown on Cu(110) by near-edge x-ray absorption fine structure (NEXAFS). A one-dimensional (1D) ordered structure of 6T…
Polar surface engineering in ultra-thin MgO(111)/Ag(111) -- possibility of metal-insulator transition and magnetism
Ryotaro Arita, Yoshiaki Tanida, Shiro Entani +3
A recent report [Kiguchi {\it et al.}, Phys. Rev. B {\bf 68}, 115402 (2003)] that the (111) surface of 5 MgO layers grown epitaxially on Ag(111) becomes metallic to reduce the elec…
Atomic and Electronic Structures of Unreconstructed Polar MgO(111) Thin Film on Ag(111)
Manabu Kiguchi, Shiro Entani, Koichiro Saiki +2
Atomic and electronic structures of a polar surface of MgO formed on Ag(111) was investigated by using reflection high energy electron diffraction (RHEED), Auger electron spectrosc…
