Observation of surface states on heavily indium-doped SnTe(111), a superconducting topological crystalline insulator
(2016) In Physical Review B (Condensed Matter and Materials Physics) 93(7).- Abstract
The topological crystalline insulator tin telluride is known to host superconductivity when doped with indium (Sn1-xInxTe), and for low indium content (x=0.04) it is known that the topological surface states are preserved. Here we present the growth, characterization, and angle resolved photoemission spectroscopy analysis of samples with much heavier In doping (up to x≈0.4), a regime where the superconducting temperature is increased nearly fourfold. We demonstrate that despite strong p-type doping, Dirac-like surface states persist.
