Change in charge density wave order beyond the Lifshitz transition in 2H-Ta\textsubscript{1}S\textsubscript{2}
Mihir Date, Jan Berges, Enrico Da Como +6
We investigate electronic instabilities in 2H-TaS\textsubscript{2} and a self-intercalated variant, 2H-Ta\textsubscript{1+}S\textsubscript{2}. In conventional samples…
The two conduction bands of monolayer CrSBr on Au
Yogal Prasad Ghimirey, Laxman Nagireddy, Cephise Cacho +2
We report the electronic structure of monolayer CrSBr exfoliated onto mica template-stripped gold substrates. Angle-resolved photoemission spectroscopy reveals charge transfer from…
Chiral charge density wave in 4Hb- and 1T-TaS: The Role of interlayer coupling
Roni Anna Gofman, Abigail Dishi, Hyeonhu Bae +12
We use micro-angle-resolved photoemission spectroscopy (micro-ARPES) to investigate chiral charge density waves (CDWs) in 4Hb-TaS with micron-scale spatial resolution. In the 1…
Charge transfer empties the flat band in 4H-TaS -- except at the surface
Mihir Date, Hyeonhu Bae, Alex Louat +5
The 4H\textsubscript{b} polytype of TaS is a natural heterostructure of H and T-type layers. Intriguing recent evidence points towards a possibly chiral superconducting ground…
Electronic structure of the interface between Au and WSe2
Laxman Nagireddy, Samuel J. Magorrian, Matthew D. Watson +5
Understanding the interface between metals and two-dimensional materials is critical for their application in electronics and for the development of metal-mediated exfoliation of l…
Emergence of a Fermi-surface in the current-driven Hidden state of 1T-TaS
Yuval Nitzav, Roni Gofman, Ilay Mangel +9
The origin of the insulating state in 1T-TaS has long been a subject of debate. A short current pulse transforms this insulating state into a metastable metallic phase. Using m…
