In this work, we performed ARPES experiments on multiple PtTe 2 samples using a synchrotron source with a wide range of photon energies and light polarizations. We observe previously unseen band crossings and features, and by comparing the photoemission at different light polarizations contrasted with theoretical calculations, we gain further insight on the nature of the observed band structure.
*ARPES measurements were supported by the US Department of Energy, Office of Science, Office of Basic Energy Sciences under award number DE-SC0018154.PtTe2 synthesis was supported by the Center for Emergent Materials, an NSF MRSEC, under award number DMR-2011876.Ivan Pelayo, Derek Bergner, Warren L Huey and Archibald Williams were supported by the Cal. State Long Beach and Ohio State University Partnership for Education and Research in Hard and Soft Materials, a National Science Foundation PREM, under Grant No. 2122199.
