On the Role of Defects in the Electronic Structure of MnBiSbTe
Daniel Nevola, Kevin F. Garrity, Nader Zaki +4
Elemental substitution is a proven method of Fermi level tuning in topological insulators, which is needed for device applications. Through static and time resolved photoemission,…
Quasiparticle Interference, quasiparticle interactions and the origin of the charge density-wave in 2H-NbSe
C. J. Arguello, E. P. Rosenthal, E. F. Andrade +10
We show that a small number of intentionally introduced defects can be used as a spectroscopic tool to amplify quasiparticle interference in 2H-NbSe, that we measure by scann…
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…
Atom-Wide Co Wires on Cu(775) at Room Temperature
Nader Zaki, Denis Potapenko, Peter D. Johnson +1
We report on a new surface phase of the Co-vicinal-Cu(111) system which exhibits self-assembled uniform Co quantum wires that are stable at 300K. STM-imaging measurements show that…
