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…
Strain-shear coupling in bilayer MoS2
Jae-Ung Lee, Sungjong Woo, Jaesung Park +3
Layered materials such as graphite and transition metal dichalcogenides have extremely anisotropic mechanical properties owing to orders of magnitude difference between in-plane an…
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…
Broken-Symmetry Quantum Hall States in Twisted Bilayer Graphene
Youngwook Kim, Jaesung Park, Intek Song +8
Twisted bilayer graphene offers a unique bilayer two-dimensional-electron system where the layer separation is only in sub-nanometer scale. Unlike Bernal-stacked bilayer, the layer…
Anomalous excitonic resonance Raman effects in few-layer MoS2
Jae-Ung Lee, Jaesung Park, Young-Woo Son +1
The resonance effects on the Raman spectra from 5 to 900 cm-1 of few-layer MoS2 thin films up to 14-layers were investigated by using six excitation energies. For the main first-or…
