| Outline of Final Research Achievements |
To explore the post-graphene materials, we have synthesised several new materials hosting functional conducting layers, such as honeycomb and square nets, by utilising a high-pressure synthesis method. We have succeeded in carrier doping in black phosphorus that consists of the stacking of phosphorus honeycomb sheets (phosphorene), by substituting phosphorus with germanium and silicon. We have also synthesised a transition metal dichalcogenide with the polar layer stacking and a new layered magnet hosting quasi 2D Dirac fermions on the bismuth square net. Furthermore, aiming at wide-range carrier doping in the newly-developed post-graphene materials, we have performed electrochemical intercalation of organic molecules. We focused on a transition metal dichalcogenide as a first target, and have successfully optimised its thermoelectric figure of merit by enhancing thermoelectric power factor and reducing the thermal conductivity.
