Diverse forms of bonding in two-dimensional Si allotropes: Nematic orbitals in the structure
Florian Gimbert, Chi-Cheng Lee, Rainer Friedlein +3
The interplay of - and -type bonding defines silicon allotropes in two- and three-dimensional forms. A novel two-dimensional phase bearing structural resembleance to a…
Competing magnetism in electrons in graphene with a single carbon vacancy
Chi-Cheng Lee, Yukiko Yamada-Takamura, Taisuke Ozaki
One intriguing finding in graphene is the vacancy-induced magnetism that highlights the interesting interaction between local magnetic moments and conduction electrons. Within dens…
First-principles study on competing phases of silicene: Effect of substrate and strain
Chi-Cheng Lee, Antoine Fleurence, Rainer Friedlein +2
The stability and electronic structure of competing silicene phases under in-plane compressive stress, either free-standing or on the ZrB(0001) surface, has been studied by fir…
A decomposition method with minimum communication amount for parallelization of multi-dimensional FFTs
Truong Vinh Truong Duy, Taisuke Ozaki
The fast Fourier transform (FFT) is undoubtedly an essential primitive that has been applied in various fields of science and engineering. In this paper, we present a decomposition…
