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…
Room Temperature In-plane <100> Magnetic Easy Axis for Fe3O4/SrTiO3(001):Nb Grown by Infrared PLD
Matteo Monti, Mikel Sanz, Mohamed Oujja +15
We examine the magnetic easy-axis directions of stoichiometric magnetite films grown on SrTiO3:Nb by infrared pulsed-laser deposition. Spin-polarized low-energy electron microscopy…
Low-Energy Electron Reflectivity of Graphene on Copper and other Substrates
N. Srivastava, Qin Gao, M. Widom +4
The reflectivity of low energy electrons from graphene on copper substrates is studied both experimentally and theoretically. Well-known oscillations in the reflectivity of electro…
Twisted Bilayer Graphene Superlattices
Yanan Wang, Zhihua Su, Wei Wu +14
Twisted bilayer graphene (tBLG) provides us with a large rotational freedom to explore new physics and novel device applications, but many of its basic properties remain unresolved…
