Observation of Gapped Topological Surface States and Isolated Surface Resonances in PdTe Ultrathin Films
Jacob Cook, Sougata Mardanya, Qiangsheng Lu +7
The superconductor PdTe is known to host bulk Dirac bands and topological surface states. The coexistence of superconductivity and topological surface states makes PdTe a p…
Lifshitz transition and van Hove singularity in a Topological Dirac Semimetal
Su-Yang Xu, Chang Liu, I. Belopolski +20
A topological Dirac semimetal is a novel state of quantum matter which has recently attracted much attention as an apparent 3D version of graphene. In this paper, we report critica…
Observation of a bulk 3D Dirac multiplet, Lifshitz transition, and nestled spin states in Na3Bi
Su-Yang Xu, Chang Liu, S. K. Kushwaha +20
Symmetry or topology protected Dirac fermion states in two and three dimensions constitute novel quantum systems that exhibit exotic physical phenomena. However, none of the studie…
Tunneling Tuned Spin Modulations in Ultrathin Topological Insulator Films
M. Neupane, A. Richardella, J. Sanchez-Barriga +18
Quantitative understanding of the relationship between quantum tunneling and Fermi surface spin polarization is key to device design using topological insulator surface states. By…
Topological Surface States and Dirac point tuning in ternary Bi2Te2Se class of topological insulators
M. Neupane, S. -Y. Xu, L. A. Wray +14
Using angle-resolved photoemission spectroscopy, we report electronic structure for representative members of ternary topological insulators. We show that several members of this f…
