Observation of Topological Crystalline Insulator phase in the lead tin chalcogenide Pb1-xSnxTe material class
Su-Yang Xu, Chang Liu, N. Alidoust +11
We perform systematic angle-resolved photoemission spectroscopic measurements on the lead tin telluride Pb1-xSnxTe pseudobinary alloy system. We show that the (001) crystalline sur…
Electron behavior in topological insulator based P-N overlayer interfaces
L. A. Wray, M. Neupane, S. -Y. Xu +8
Topological insulators (TIs) are novel materials that manifest spin-polarized Dirac states on their surfaces or at interfaces made with conventional matter. We have measured the el…
Anomalous spin-momentum locked two-dimensional states in the vicinity of a topological phase transition
Su-Yang Xu, M. Neupane, Chang Liu +12
We perform spin-resolved and spin-integrated angle-resolved photoemission spectroscopy measurements on a series of compositions in the BiTl(S1-xSex)2 system, focusing on x-values i…
Single-Dirac-Cone topological surface states on pseudo-IV-VI-semimetal/semiconductors: Thallium-based III-V-VI2 Ternary Chalcogenides
H. Lin, R. S. Markiewicz, L. A. Wray +3
We have investigated several classes of strong spin-orbit chalcogenides related to the (Pb,Sn)Te series studied in connection with the Dirac fermion physics in the 1980s. Our first…
