Single Crystal Growth and Transport Properties of van der Waals Materials Te ( = Ti, Zr, Hf)
Yuto Hasuo, Takahiro Urata, Masaaki Araidai +3
Monolayers of Te (/ = Ti, Zr, Hf) were theoretically predicted to be two-dimensional topological insulators, but little has been known about the physical properties o…
Negative-charge-storing mechanism of potassium-ion electrets used for vibration-powered generators: Microscopic study of a-SiO2 with and without potassium atoms
Toru Nakanishi, Takeshi Miyajima, Kenta Chokawa +5
A potassium-ion electret, which is a key element of vibration-powered microelectromechanical generators, can store negative charge almost permanently. However, the mechanism by whi…
Influence of edge magnetization and electric fields on zigzag silicene, germanene and stanene nanoribbons
Ayami Hattori, Keiji Yada, Masaaki Araidai +3
Using a multi-orbital tight-binding model, we have studied the edge states of zigzag silicene, germanene, and stanene nanoribbons (ZSiNRs, ZGeNRs and ZSnNRs, respectively) in the p…
Edge states of hydrogen terminated monolayer materials: silicene, germanene and stanene ribbons
Ayami Hattori, Sho Tanaya, Keiji Yada +5
We investigate the energy dispersion of the edge states in zigzag silicene, germanene and stanene nanoribbons with and without hydrogen termination based on a multi-orbital tight-b…
Field emission mechanisms of graphitic nanostructures
Masaaki Araidai, Yasuhiro Nakamura, Kazuyuki Watanabe
Field emission (FE) and the electronic-states origin of graphitic nanostructures were investigated by first-principles calculations based on time-dependent density-functional theor…
