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…
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…
Electronic properties of metal induced gap states at insulator/metal interfaces -- dependence on the alkali halide and the possibility of excitonic mechanism of superconductivity
Ryotaro Arita, Yoshiaki Tanida, Kazuhiko Kuroki +1
Motivated from the experimental observation of metal induced gap states (MIGS) at insulator/metal interfaces by Kiguchi {\it et al.} [Phys. Rev. Lett. {\bf 90}, 196803 (2003)], we…
Metal-Induced Gap States at Well Defined Alkali-Halide/Metal Interfaces
Manabu Kiguchi, Ryotaro Arita, Genki Yoshikawa +5
In order to search for states specific to insulator/metal interfaces, we have studied epitaxially grown interfaces with element-selective near edge X-ray absorption fine structure…
Image-potential band-gap narrowing at a metal/semiconductor interface
Ryotaro Arita, Yoshiaki Tanida, Kazuhiko Kuroki +1
GW approximation is used to systematically revisit the image-potential band-gap narrowing at metal/semiconductor interfaces proposed by Inkson in the 1970's. Here we have questione…
