Simultaneous Control of Bandfilling and Bandwidth in Electric Double-Layer Transistor Based on Organic Mott Insulator -(BEDT-TTF)Cu[N(CN)]Cl
Yoshitaka Kawasugi, Hiroshi M. Yamamoto
The physics of quantum many-body systems have been studied using bulk correlated materials, and recently, moiré superlattices formed by atomic bilayers have appeared as a novel pla…
Pressure-induced phase switching of the Shubnikov de Haas oscillations in molecular Dirac fermion system (BETS)I
Yoshitaka Kawasugi, Hikaru Masuda, Masashi Uebe +4
We report on the Shubnikov de Haas (SdH) oscillations in the quasi two-dimensional molecular conductor (BETS)I [BETS: bis(ethylenedithio)tetraselenafulvalene] lamin…
Non-Fermi-liquid behavior and doping asymmetry in an organic Mott insulator interface
Yoshitaka Kawasugi, Kazuhiro Seki, Jiang Pu +4
High- superconductors show anomalous transport properties in their normal states, such as the bad-metal and pseudogap behaviors. To discuss their origins, it is importan…
Two-dimensional ground-state mapping of a Mott-Hubbard system in a flexible field-effect device
Yoshitaka Kawasugi, Kazuhiro Seki, Satoshi Tajima +5
A Mott insulator sometimes induces unconventional superconductivity in its neighbors when doped and/or pressurized. Because the phase diagram should be strongly related to the micr…
Critical Behavior in Doping-Driven MetalInsulator Transition on Single-Crystalline Organic Mott-FET
Yoshiaki Sato, Yoshitaka Kawasugi, Masayuki Suda +2
We present the carrier transport properties in the vicinity of a doping-driven Mott transition observed at a field-effect transistor (FET) channel using a single crystal of the typ…
Electron-hole doping asymmetry of Fermi surface reconstructed in a simple Mott insulator
Yoshitaka Kawasugi, Kazuhiro Seki, Yusuke Edagawa +6
It is widely recognised that the effect of doping into a Mott insulator is complicated and unpredictable, as can be seen by examining the Hall coefficient in high cupra…
