Discovery of nanographene for hydrogen storage solving low reversibility issues
Gagus Ketut Sunnardianto, Yusuf Wicaksono, Halimah Harfah +1
We found good reversibility of hydrogen uptake-release in vacancy-centered hexagonal armchair nanographene (VANG) based on density functional theory calculation. VANG has a triply…
Theoretical Analysis on the Stability of 1-Pyrenebutanoic Acid Succinimidyl Ester Adsorbed on Graphene
Yasuhiro Oishi, Hirotsugu Ogi, Satoshi Hagiwara +2
The adsorbed structure of 1-pyrenebutanoic acid succinimidyl ester (PASE) on graphene was investigated based on density functional theory. We found two locally stable structures: a…
Ultimate In-plane Magnetoresistance Ratio of Graphene by Controlling the Gapped Dirac Cone through Pseudospin
Yusuf Wicaksono, Halimah Harfah, Gagus Ketut Sunnardianto +2
$\require{mediawiki-texvc}$ A theoretical study is presented on the in-plane conductance of graphene that is partially sandwiched by Ni(111) slabs with a finite size and atom-scale…
High magnetoresistance of hexagonal boron nitride-graphene heterostructure-based MTJ through excited-electron transmission
Halimah Harfah, Yusuf Wicaksono, Gagus Ketut Sunnardianto +2
This work presents an ab-initio study of a few-layers hexagonal boron nitride (hBN) and hBN-graphene heterostructure sandwiched between Ni(111) layers. The aim of this study is to…
Zero-energy modes in super-chiral nanographene networks of phenalenyl-tessellation molecules
Naoki Morishita, Koichi Kusakabe
We have derived a general rule for the appearance of zero-energy modes in super-chiral defective nanographene. This so-called "super-zero-sum rule" defines the appearance of zero m…
Material Optimization of Potential High- Superconducting Single-layer Cuprates
Shingo Teranishi, Kazutaka Nishiguchi, Koichi Kusakabe
We investigated the material parameters of several single-layer cuprates, including those with fluorinated buffer layers, with the aim of identifying possible high-temperature supe…
