Femtosecond phase-transition in hard x-ray excited bismuth
M. Makita, I. Vartiainen, I. Mohacs +19
The evolution of the bismuth crystal structure upon excitation of its A phonon has been intensely studied with short pulse optical lasers. Here we present the first-time obs…
Intrinsic origin of the two-dimensional electron gas at polar oxide interfaces
M. L. Reinle-Schmitt, C. Cancellieri, D. Li +8
The predictions of the polar catastrophe scenario to explain the occurrence of a metallic interface in heterostructures of the solid solution(LaAlO)(SrTiO) (L…
Depth Dependence of the Structural Phase Transition of SrTiO_3 Studied with β-NMR and Grazing Incidence X-ray Diffraction
Z. Salman, M. Smadella, W. A. MacFarlane +7
We present an investigation of the near-surface tetragonal phase transition in SrTiO3, using the complementary techniques of beta-detected nuclear magnetic resonance and grazing-in…
Evolution of the interfacial structure of LaAlO3 on SrTiO3
S. A. Pauli, S. J. Leake, B. Delley +7
The evolution of the atomic structure of LaAlO3 grown on SrTiO3 was investigated using surface x-ray diffraction in conjunction with model-independent, phase-retrieval algorithms b…
Graphene on Ru(0001): A corrugated and chiral structure
D. Martoccia, M. Bjoerck, C. M. Schlepuetz +5
We present a structural analysis of the graphene/Ru(0001) system obtained by surface x-ray diffraction. The data were fit using Fourier-series expanded displacement fields from an…
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…
