Jahn-Teller stabilization of a "polar" metal oxide surface: Fe3O4(001)
R. Pentcheva, F. Wendler, H. L. Meyerheim +3
Using ab initio thermodynamics we compile a phase diagram for the surface of Fe3O4(001) as a function of temperature and oxygen pressures. A hitherto ignored polar termination with…

Unit cell of graphene on Ru(0001): a 25 x 25 supercell with 1250 carbon atoms
D. Martoccia, P. R. Willmott, T. Brugger +10
The structure of a single layer of graphene on Ru(0001) has been studied using surface x-ray diffraction. A surprising superstructure has been determined, whereby 25 x 25 graphene…
