Correlation between surface rumpling and structural phase transformation of SrTiO3
S. Singh, Te-Yu Chien, J. R. Guest +1
We present x-ray reflectivity, x-ray diffraction and atomic force microscopy measurements of single crystal SrTiO3 taken as a function of temperature. We found a rumpling transform…
Graphene formed on SiC under various environments: Comparison of Si-face and C-face
N. Srivastava, Guowei He, Luxmi +3
The morphology of graphene on SiC {0001} surfaces formed in various environments including ultra-high vacuum, 1 atm of argon, and 10^-6 to 10^-4 Torr of disilane is studied by atom…
Ultrathin BaTiO3 templates for multiferroic nanostructures
Xumin Chen, Seolun Yang, Ji-Hyun Kim +11
Structural, electronic and dielectric properties of high-quality ultrathin BaTiO3 films are investigated. The films, which are grown by ozone-assisted molecular beam epitaxy on Nb-…
Control of octahedral rotations in (LaNiO)/(SrMnO) superlattices
S. J. May, C. R. Smith, J. -W. Kim +3
Oxygen octahedral rotations have been measured in short-period (LaNiO)/(SrMnO) superlattices using synchrotron diffraction. The in-plane and out-of-plane bond angle…
