Realization of 5 h/e^2 with graphene quantum Hall resistance array
Jaesung Park, Wan-Seop Kim, Dong-Hun Chae
We report on realization of 10 quantum Hall devices in series fabricated using epitaxial graphene on silicon carbide. Precision measurements with a resistance bridge indicates that…
Quantum mechanical current-to-voltage conversion with quantum Hall resistance array
Dong-Hun Chae, Mun-Seog Kim, Wan-Seop Kim +2
Accurate measurement of the electric current requires a stable and calculable resistor for an ideal current to voltage conversion. However, the temporal resistance drift of a physi…
Asymmetric Electron-Hole Decoherence in Ion-Gated Epitaxial Graphene
Kil-Joon Min, Jaesung Park, Wan-Seop Kim +1
We report on asymmetric electron-hole decoherence in epitaxial graphene gated by an ionic liquid. The observed negative magnetoresistance near zero magnetic field for different gat…
Laser-induced disassembly of a graphene single crystal into a nano-crystalline network
Benjamin Krauss, Timm Lohmann, Dong-Hun Chae +3
We report about investigations of time-dependent structural modifications in single crystal graphene due to laser irradiation even at moderate power levels of 1mW in a diffraction…
