Strongly correlated superconductivity in a copper-based metal-organic framework with a perfect kagome lattice
T. Takenaka, K. Ishihara, M. Roppongi +17
Metal-organic frameworks (MOFs), which are self-assemblies of metal ions and organic ligands, provide a tunable platform to search a new state of matter. A two-dimensional (2D) per…
Two-dimensional hole gas in organic semiconductors
Naotaka Kasuya, Junto Tsurumi, Toshihiro Okamoto +2
A highly conductive metallic gas that is quantum mechanically confined at a solid-state interface is an ideal platform to explore nontrivial electronic states that are otherwise in…
Terahertz Raman spectroscopy probe of intermolecular vibration in high-mobility organic semiconductors under uniaxial strain
Junto Tsurumi, Takayoshi Kubo, Hiroyuki Ishii +4
Terahertz Raman spectroscopy was performed on high-mobility organic single-crystal semiconductors, by which the phonon energy at the Gamma point was qualified as a function of exte…
Hall effect of quasi-hole gas in organic single-crystal transistors
J. Takeya, K. Tsukagoshi, Y. Aoyagi +2
Hall effect is detected in organic field-effect transistors, using appropriately shaped rubrene (C42H28) single crystals. It turned out that inverse Hall coefficient, having a posi…
Effects of polarized organosilane self-assembled monolayers on organic single-crystal field-effect transistors
J. Takeya, T. Nishikawa, T. Takenobu +7
The surface conductivity is measured by a four-probe technique for pentacene and rubrene single-crystals laminated on polarized and nearly unpolarized molecular monolayers with app…
Field-induced charge transport at the surface of pentacene single crystals: a method to study charge dynamics of 2D electron systems in organic crystals
J. Takeya, C. Goldmann, S. Haas +3
A method has been developed to inject mobile charges at the surface of organic molecular crystals, and the DC transport of field-induced holes has been measured at the surface of p…
