Unconventional thermal conductivity of suspended zigzag graphene nanomesh
Takamoto Yokosawa, Tomohiro Matsui
Compared to the study of graphene itself, the study of nano-structured graphene is rather limited because it is difficult to prepare atomically ordered edges. In this study, we hav…
Termination of Graphene Edges Created by Hydrogen and Deuterium Plasmas
Taisuke Ochi, Masahiro Kamada, Takamoto Yokosawa +3
Edge engineering is important for both fundamental research and applications as the device size decreases to nanometer scale. This is especially the case for graphene because a gra…
Introducing Corrections to the Reflectance of Graphene by Light Emission
Ken-ichi Sasaki, Kenichi Hitachi, Masahiro Kamada +3
Monolayer graphene absorbs 2.3 percent of the incident visible light. This 'small' absorption has been used to emphasize the visual transparency of graphene, but it in fact means t…
Nanoscale Fabrication of Graphene by Hydrogen-Plasma Etching
Takamoto Yokosawa, Masahiro Kamada, Taisuke Ochi +4
Graphene is attracting vast interest due to its superior electronic and mechanical properties. However, structure and electronic properties of its edge are often neglected, althoug…
Two-dimensional superconductivity of the Ca-intercalated graphene on SiC: vital role of the interface between monolayer graphene and the substrate
Haruko Toyama, Ryota Akiyama, Satoru Ichinokura +10
Ca-intercalation has opened a way for superconductivity in graphene on SiC. However, the atomic and electronic structures being critical for superconductivity are still under discu…
A Simple Experimental Setup for Simultaneous Superfluid-response and Heat-capacity Measurements for Helium in Confined Geometries
Jun Usami, Ryo Toda, Sachiko Nakamura +2
Torsional oscillator (TO) is an experimental technique which is widely used to investigate superfluid responses in helium systems confined in porous materials or adsorbed on substr…
