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 $^…
Growth Structure and Work Function of Bilayer Graphene on Pd(111)
Y. Murata, S. Nie, A. Ebnonnasir +5
Using in situ low-energy electron microscopy and density functional theory, we studied the growth structure and work function of bilayer graphene on Pd(111). Low-energy electron di…
Viable thermionic emission from graphene-covered metals
Elena Starodub, Norman C. Bartelt, Kevin F. McCarty
Thermionic emission from monolayer graphene grown on representative transition metals, Ir and Ru, is characterized by low-energy electron microscopy (LEEM). Work functions were det…
Extraordinary epitaxial alignment of graphene islands on Au(111)
Joseph M. Wofford, Elena Starodub, Andrew L. Walter +7
Pristine, single-crystalline graphene displays a unique collection of remarkable electronic properties that arise from its two-dimensional, honeycomb structure. Using in-situ low-e…
In-plane orientation effects on the electronic structure, stability and Raman scattering of monolayer graphene on Ir(111)
Elena Starodub, Aaron Bostwick, Luca Moreschini +4
We employ angle-resolved photoemission spectroscopy (ARPES) to investigate the electronic structures of two rotational variants of epitaxial, single-layer graphene on Ir(111). As g…
Oxidation of graphene on metals
Elena Starodub, Norman C. Bartelt, Kevin F. McCarty
We use low-energy electron microscopy to investigate how graphene is removed from Ru(0001) and Ir(111) by reaction with oxygen. We find two mechanisms on Ru(0001). At short times,…
