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,…
Temperature-Driven Topological Transition in 1T'-MoTe2
Ayelet Notis Berger, Erick Andrade, Alex Kerelsky +12
The topology of Weyl semimetals requires the existence of unique surface states. Surface states have been visualized in spectroscopy measurements, but their connection to the topol…
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…
The failure of DFT-based computations for a stepped-substrate-supported correlated Co wire
Nader Zaki, Hyowon Park, Richard M. Osgood +2
Density functional theory (DFT) has been immensely successful in its ability to predict physical properties, and, in particular, structures of condensed matter systems. Here, howev…
