On the rotational alignment of graphene domains grown on Ge(110) and Ge(111)
P. C. Rogge, M. E. Foster, J. M. Wofford +3
We have used low-energy electron diffraction and microscopy to compare the growth of graphene on hydrogen-free Ge(111) and Ge(110) from an atomic carbon flux. Growth on Ge(110) lea…
Real-time observation of epitaxial graphene domain reorientation
Paul C. Rogge, Konrad Thürmer, Michael E. Foster +3
Graphene films grown by vapor deposition tend to be polycrystalline due to the nucleation and growth of islands with different in-plane orientations. Here, using low-energy electro…
Influence of lattice orientation on growth and structure of graphene on Cu(001)
Joseph M. Wofford, Shu Nie, Konrad Thürmer +2
We have used low-energy electron microscopy and diffraction to examine the significance of lattice orientation in graphene growth on Cu(001). Individual graphene domains undergo an…
Metal-insulator transition of the reduced surface of yttria-stabilized zirconia near Pt electrodes
D. A. Siegel, F. El Gabaly, K. F. McCarty +1
The electrochemical reactions of solid oxide fuel cells occur in the region where gas-phase species, electrode, and electrolyte coincide. When the electrode is an ionic insulator a…
Order-disorder phase transition on the (100) surface of magnetite
Norman C. Bartelt, Shu Nie, Elena Starodub +5
Using low-energy electron diffraction, we show that the room-temperature reconstruction of FeO(100) reversibly disorders at 450 $^…
Anomalously Strong 2D Band Intensity in Twisted Bilayer Graphene: Raman Evidence for Doubly Degenerate Dirac Band
Yanan Wang, Zhihua Su, Wei Wu +8
We report the observation of anomalously strong 2D band in twisted bilayer graphene (tBLG) with large rotation angles under 638-nm and 532-nm visible laser excitation. The 2D band…
