Geometric Brownian motion with random observation time as generalization of the double Pareto distribution
Ken Yamamoto, Takashi Bando, Hirokazu Yanagawa +1
We study the probability distribution of the value of geometric Brownian motion at the stochastic observation time. It is known that the exponentially distributed observation time…
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…
