Observation of dichotomic field-tunable electronic structure in twisted monolayer-bilayer graphene
Hongyun Zhang, Qian Li, Youngju Park +18
Twisted bilayer graphene (tBLG) provides a fascinating platform for engineering flat bands and inducing correlated phenomena. By designing the stacking architecture of graphene lay…
Floquet engineering of black phosphorus upon below-gap pumping
Shaohua Zhou, Changhua Bao, Benshu Fan +6
Time-periodic light field can dress the electronic states and lead to light-induced emergent properties in quantum materials. While below-gap pumping is regarded favorable for Floq…
Angle-resolved photoemission spectroscopy
Hongyun Zhang, Tommaso Pincelli, Chris Jozwiak +4
For solid-state materials, the electronic structure, E(k), is critical in determining a crystal's physical properties. By experimentally detecting the electronic structure, the fun…
Experimental evidence of plasmarons and effective fine structure constant in electron-doped graphene/h-BN heterostructure
Hongyun Zhang, Shuopei Wang, Eryin Wang +13
Electron-electron interaction is fundamental in condensed matter physics and can lead to composite quasiparticles called plasmarons, which strongly renormalize the dispersion and c…
Coexistence of extended flat band and Kekulé order in Li-intercalated graphene
Changhua Bao, Hongyun Zhang, Xi Wu +6
Doping graphene near the 1/4 filling to shift the extended flat band and van Hove singularity below E has been highly desirable. Here we report the experimental observation of…
Experimental evidence of chiral symmetry breaking in Kekulé-ordered graphene
Changhua Bao, Hongyun Zhang, Teng Zhang +13
The low-energy excitations of graphene are relativistic massless Dirac fermions with opposite chiralities at valleys K and K'. Breaking the chiral symmetry could lead to gap openin…
Self-energy dynamics and mode-specific phonon threshold effect in a Kekulé-ordered graphene
Hongyun Zhang, Changhua Bao, Michael Schüler +7
Electron-phonon interaction and related self-energy are fundamental to both the equilibrium properties and non-equilibrium relaxation dynamics of solids. Although electron-phonon i…
