Reconciliation of local and long range tilt correlations in underdoped La2-xBaxCuO4
Emil S. Bozin, Ruidan Zhong, Kevin R. Knox +4
A long standing puzzle regarding the disparity of local and long range CuO6 octahedral tilt correlations in the underdoped regime of La2-xBaxCuO4 is addressed by utilizing compleme…
The Nature of Surface States on Vicinal Cu (775): An STM and Photoemission Study
Nader Zaki, Kevin Knox, Richard M. Osgood +4
We report ARPES and a set of in situ STM measurements on a narrow-terrace-width vicinal Cu(111) crystal surface, Cu(775), whose vicinal cut lies close to the transition between ter…
Cu(IrCr)S: a model system for studying nanoscale phase coexistence at the metal-insulator transition
E. S. Bozin, K. R. Knox, P. Juhas +3
Increasingly, nanoscale phase coexistence and hidden broken symmetry states are being found in the vicinity of metal-insulator transitions (MIT), for example, in high temperature s…
Local Structural Evidence for Strong Electronic Correlations in LiRhO Spinel
K. R. Knox, A. M. M. Abeykoon, H. Zheng +5
The local structure of the spinel LiRhO has been studied using atomic pair distribution function (PDF) analysis of powder x-ray diffraction data. This measurement is sensit…
Trapping Surface Electrons on Graphene Layers and Islands
D. Niesner, Th. Fauster, J. I. Dadap +7
We report the use of time- and angle-resolved two-photon photoemission to map the bound, unoccupied electronic structure of the weakly coupled graphene/Ir(111) system. The energy,…
Making ARPES Measurements on Corrugated Monolayer Crystals: Suspended Exfoliated Single-Crystal Graphene
Kevin R. Knox, Andrea Locatelli, Mehmet B. Yilmaz +6
Free-standing exfoliated monolayer graphene is an ultra-thin flexible membrane, which exhibits out of plane deformation or corrugation. In this paper, a technique is described to m…
