Orbital superconductivity, defects and pinned nematic fluctuations in the doped iron chalcogenide FeSe${}_{0.45}$Te${}_{0.55}$

Saheli Sarkar, John Van Dyke, Peter Sprau +5

We demonstrate that the differential conductance, $dI/dV$, measured via spectroscopic imaging scanning tunneling microscopy in the doped iron chalcogenide FeSe${}_{0.45}$Te${}_{0.55}$,…
