    • Bounds on nanoscale nematicity in single-layerFeSe/SrTiO3 

      Huang, Dennis; Webb, Tatiana A.; Fang, Shiang; Song, Can-Li; Chang, Cui-Zu; Moodera, Jagadeesh S.; Kaxiras, Efthimios; Hoffman, Jennifer Eve (American Physical Society (APS), 2016)
      We use scanning tunneling microscopy (STM) and quasiparticle interference (QPI) imaging to investigate the low-energy orbital texture of single-layer FeSe/SrTiO3. We develop a T -matrix model of multiorbital QPI to disentangle ...

    • Dumbbell Defects in FeSe Films: A Scanning Tunneling Microscopy and First-Principles Investigation 

      Huang, Dennis; Webb, Tatiana A.; Song, Can-Li; Chang, Cui-Zu; Moodera, Jagadeesh S.; Kaxiras, Efthimios; Hoffman, Jennifer Eve (American Chemical Society (ACS), 2016)
      The properties of iron-based superconductors (Fe-SCs) can be varied dramatically with the introduction of dopants and atomic defects. As a pressing example, FeSe, parent phase of the highest-Tc Fe-SC, exhibits prevalent ...

    • Revealing the Empty-State Electronic Structure of Single-Unit-Cell FeSe/SrTiO3 

      Huang, Dennis; Song, Can-Li; Webb, Tatiana A.; Fang, Shiang; Chang, Cui-Zu; Moodera, Jagadeesh S.; Kaxiras, Efthimios; Hoffman, Jennifer Eve (American Physical Society (APS), 2015)
      We use scanning tunneling spectroscopy to investigate the filled and empty electronic states of superconducting single-unit-cell FeSe deposited on SrTiO3(001). We map the momentum-space band structure by combining quasiparticle ...
