From Type-II Triply Degenerate Nodal Points and Three-Band Nodal Rings to Type-II Dirac Points in Centrosymmetric Zirconium Oxide
Ting-Ting Zhang, Zhi-Ming Yu, Wei Guo +3
Using first-principles calculations, we report that ZrO is a topological material with the coexistence of three pairs of type-II triply degenerate nodal points (TNPs) and three nod…
Emergence of Frohlich polaron from interlayer electron-phonon coupling in van der Waals heterostructure
Chaoyu Chen, Jose Avila, Shuopei Wang +8
Van der Waals heterostructures, vertical stacks of layered materials, offer newopportunities for novel quantum phenomena which are absent in their constituent components. Here we r…
Emergence of Tertiary Dirac Points in Graphene Moiré Superlattices
Guorui Chen, Mengqiao Sui, Duoming Wang +10
The electronic structure of a crystalline solid is largely determined by its lattice structure. Recent advances in van der Waals solids, artificial crystals with controlled stackin…
A graphene Zener-Klein transistor cooled by a hyperbolic substrate
W. Yang, S. Berthou, X. Lu +11
Engineering of cooling mechanisms is a bottleneck in nanoelectronics. Whereas thermal exchanges in diffusive graphene are mostly driven by defect assisted acoustic phonon scatterin…
Electronic structure of transferred graphene/h-BN van der Waals heterostructures with nonzero stacking angles by nano-ARPES
Eryin Wang, Guorui Chen, Guoliang Wan +8
In van der Waals heterostructures, the periodic potential from the Moiré superlattice can be used as a control knob to modulate the electronic structure of the constituent material…
