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…
Moiré Modulated Lattice Strain and Thickness-Dependent Lattice Expansion in Epitaxial Ultrathin Films of PdTe
Jacob Cook, Dorri Halbertal, Qiangsheng Lu +4
We report the epitaxial growth of PdTe ultrathin films on topological insulator BiSe. A prominent Moiré pattern was observed in STM measurements. The Moiré periodicity…
Multi-layered atomic relaxation in van der Waals heterostructures
Dorri Halbertal, Lennart Klebl, Valerie Hsieh +6
When two-dimensional van der Waals materials are stacked to build heterostructures, moiré patterns emerge from twisted interfaces or from mismatch in lattice constant of individual…
Observation of Unpinned Two-Dimensional Dirac States in Antimony Single Layers with Phosphorene Structure
Qiangsheng Lu, Matthew Snyder, Kyle Y. Chen +10
The discovery of graphene has stimulated enormous interest in two-dimensional (2D) electron gas with linear band structure. 2D Dirac materials possess many intriguing physical prop…
Giant Topological Hall Effect in van der Waals Heterostructures of CrTe2/Bi2Te3
Xiaoqian Zhang, Siddhesh C. Ambhire, Qiangsheng Lu +11
Discoveries of interfacial topological Hall effect (THE) provide an ideal platform for exploring physics arising from the interplay between topology and magnetism. The interfacial…
Dirac Fermion Cloning, Moir Flat Bands and Magic Lattice Constants in Epitaxial Monolayer Graphene
Qiangsheng Lu, Ching-Kai Chiu, Congcong Le +10
Tuning interactions between Dirac states in graphene has attracted enormous interest because it can modify the electronic spectrum of the two-dimensional material, enhance electron…
Observation of Symmetry-Protected Dirac States in Nonsymmorphic -Antimonene
Qiangsheng Lu, Kyle Y. Chen, Matthew Snyder +6
Two-dimensional (2D) Dirac states with linear band dispersion have attracted enormous interest since the discovery of graphene. However, to date, 2D Dirac semimetals are still very…
