Factors influencing graphene growth on metal surfaces
E. Loginova, N. C. Bartelt, P. J. Feibelman +1
Graphene forms from a relatively dense, tightly-bound C-adatom gas, when elemental C is deposited on or segregates to the Ru(0001) surface. Nonlinearity of the graphene growth rate…

Kinetics and thermodynamics of carbon segregation and graphene growth on Ru(0001)
Kevin F. McCarty, Peter J. Feibelman, Elena Loginova +1
We measure the concentration of carbon adatoms on the Ru(0001) surface that are in equilibrium with C atoms in the crystal's bulk by monitoring the electron reflectivity of the sur…

Defects of graphene on Ir(111): rotational domains and ridges
Elena Loginova, Shu Nie, Konrad Thurmer +2
We use low-energy electron microscopy (LEEM), low-energy electron diffraction (LEED) and scanning tunneling microscopy (STM) to study different orientations of single-layer graphen…
