Observation of near EF Fermi-arc van Hove singularity with prominent coupling to phonon in a van der Waals coupled Weyl semimetal
Z. Wang, Cheng-Yi Huang, Chia-Hsiu Hsu +7
A van der Waals coupled Weyl semimetal material NbIrTe4 is investigated by combining scanning tunneling microscopy/spectroscopy and first principles calculations. We observe a shar…
Quantum oscillations with magnetic hysteresis observed in CeTe thin films
Mori Watanabe, Sanghyun Lee, Takuya Asano +7
We have performed magnetotransport measurements in CeTe thin films down to . It is known that CeTe has two magnetic transitions at $T_{\rm N1} \approx 3~{\…
Dirac mass generation from crystal symmetry breaking on the surfaces of topological crystalline insulators
Ilija Zeljkovic, Yoshinori Okada, Maksym Serbyn +12
The tunability of topological surface states (SS) and controllable opening of the Dirac gap are of fundamental and practical interest in the field of topological materials. In topo…
Observation of Dirac node formation and mass acquisition in a topological crystalline insulator
Yoshinori Okada, Maksym Serbyn, Hsin Lin +13
In the recently discovered topological crystalline insulators (TCIs), topology and crystal symmetry intertwine to create surface states with a unique set of characteristics. Among…
Ripple modulated electronic structure of a 3D topological insulator
Yoshinori Okada, Wenwen Zhou, D. Walkup +3
3D topological insulators, similar to the Dirac material graphene, host linearly dispersing states with unique properties and a strong potential for applications. A key, missing el…
Visualizing Landau levels of Dirac electrons in a one dimensional potential
Yoshinori Okada, Wenwen Zhou, Chetan. Dhital +5
Using scanning tunneling spectroscopy we have measured the response of Dirac electrons in a magnetic field to the presence of a well-defined smoothly varying 1D periodic potential.…
