Dimensional crossover and symmetry transformation of the charge density waves in VSe2
P. Chen, Y. -H. Chan, R. -Y. Liu +5
Collective phenomena in solids can be sensitive to the dimensionality of the system; a case of special interest is VSe2, which shows a (r7 x r3) charge density wave (CDW) in the si…
Evidence of high-temperature exciton condensation in a two-dimensional semimetal
Qiang Gao, Yang-hao Chan, Yuzhe Wang +10
Electrons and holes can spontaneously form excitons and condense in a semimetal or semiconductor, as predicted decades ago. This type of Bose condensation can happen at much higher…
Edge States of α-Bismuthene Nanostructures
Sara Salehitaleghani, Tobias Maerkl, Pawel J Kowalczyk +5
We present a systematic investigation of the edge states of two-dimensional α-bismuthene (α-Bi) structures self-assembled on HOPG substrates, using scanning tunnelling microscopy a…
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…
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…
Strong band kinks in magic-thickness Yb films arising from interfacial electron-phonon coupling
Yi Wu, Yuan Fang, Shuyi Zhou +7
Interfacial electron-phonon coupling in ultrathin films has attracted much interest; it can give rise to novel effects and phenomena, including enhanced superconductivity. Here we…
