Dynamic nuclear polarization induced by breakdown of fractional quantum Hall effect
Minoru Kawamura, Masashi Ono, Yoshiaki Hashimoto +3
We study dynamic nuclear polarization (DNP) induced by breakdown of the fractional quantum Hall (FQH) effect. We find that voltage-current characteristics depend on current sweep r…
Fabrication of graphene nanoribbon by local anodic oxidation lithography using atomic force microscope
S. Masubuchi, M. Ono, K. Yoshida +2
We conducted local anodic oxidation (LAO) lithography in single-layer, bilayer, and multilayer graphene using tapping-mode atomic force microscope. The width of insulating oxidized…
Electrical polarization of nuclear spins in a breakdown regime of quantum Hall effect
M. Kawamura, H. Takahashi, K. Sugihara +3
We have developed a method for electrical polarization of nuclear spins in quantum Hall systems. In a breakdown regime of odd-integer quantum Hall effect (QHE), excitation of elect…
