Surface phases of the transition-metal dichalcogenide IrTe2
Chen Chen, Jisun Kim, Yifan Yang +3
Transition-metal dichalcogenide IrTe2 has attracted attention because of striped lattice, charge ordering and superconductivity. We have investigated the surface structure of IrTe2…
Effect of Negative Pressure on the Prototypical Itinerant Magnet MnSi
C. Dhital, M. A Khan, M. Saghayezhian +4
The evolution of the magnetic and charge transport properties of itinerant magnetic metal MnSi with the substitution of Al and Ga on the Si site is investigated. We observe an incr…
Hidden Phases Revealed at the Surface of Double-Layered Sr3(Ru1-xMnx)2O7
Chen Chen, Jisun Kim, V. B. Nascimento +8
Double-layered Sr3Ru2O7 has received phenomenal consideration because it exhibits a plethora of exotic phases when perturbed. New phases emerge with the application of pressure, ma…
Interrogating the superconductor Ca10(Pt4As8)(Fe2-xPtxAs2)5 Layer-by-layer
Jisun Kim, Hyoungdo Nam, Guorong Li +7
Ever since the discovery of high-Tc superconductivity in layered cuprates, the roles that individual layers play have been debated, due to difficulty in layer-by-layer characteriza…
Surface terminations and layer-resolved spectroscopy in 122 iron pnictide superconductors
Ang Li, J. -X. Yin, Jihui Wang +13
The surface terminations of 122-type alkaline earth metal iron pnictides AEFe2As2 (AE = Ca, Ba) are investigated with scanning tunneling microscopy/spectroscopy (STM/STS). Cleaving…
