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…

Suppression of noise in graphene due to non-scalar mobility fluctuations induced by impurity motion

Masahiro Kamada, Weijun Zeng, Antti Laitinen +5

Low frequency resistance variations due to mobility fluctuations is one of the key factors of noise in metallic conductors. According to theory, such noise in a two-dimension…

Electrical low-frequency noise due to surface diffusion of scatterers on an ultra low noise graphene platform

Masahiro Kamada, Antti Laitinen, Weijun Zeng +5

Low-frequency noise is ubiquitous, even in high-end electronic devices. For qubits such noise results in decrease of their coherence times. Recently, it was found that adso…

Strong magnetoresistance in a graphene Corbino disk at low magnetic fields

Masahiro Kamada, Vanessa Gall, Jayanta Sarkar +4

We have measured magnetoresistance of suspended graphene in the Corbino geometry at magnetic fields up to T, i.e., in a regime uninfluenced by Shubnikov-de Haas oscillati…

Topologically protected mobile solid He on carbon nanotube

Igor Todoshchenko, Masahiro Kamada, Jukka-Pekka Kaikkonen +7

Low dimensional fermionic quantum systems are exceptionally interesting because they reveal distinctive physical phenomena, including among others, topologically protected excitati…
