Phonon-assisted inter-valley scattering determines ultrafast exciton dynamics in MoSe bilayers
Sophia Helmrich, Kevin Sampson, Di Huang +10
While valleys (energy extrema) are present in all band structures of solids, their preeminent role in determining exciton resonances and dynamics in atomically thin transition meta…
Substrate dopant induced electronic inhomogeneity in epitaxial bilayer graphene
Shuai Zhang, Di Huang, Lehua Gu +2
Two-dimensional (2D) materials have become a new territory for exploring novel properties and functionalities because of their superior tunability. The unprecedented tunability of…
Giant and nonreciprocal second harmonic generation from layered antiferromagnetism in bilayer CrI3
Zeyuan Sun, Yangfan Yi, Tiancheng Song +14
Layered antiferromagnetism is the spatial arrangement of ferromagnetic layers with antiferromagnetic interlayer coupling. Recently, the van der Waals magnet, chromium triiodide (Cr…
Chiral selection rules for multi-photon processes in two-dimensional honeycomb materials
Jingxin Cheng, Di Huang, Tao Jiang +4
We examined the chirality dependent optical selection rules in two-dimensional monolayer materials with the honeycomb lattice, and based on symmetry argument, we generalized these…
Doping Induced Second Harmonic Generation in Centrosymmetric Graphene from Quadrupole Response
Yu Zhang, Di Huang, Yuwei Shan +8
For centrosymmetric materials such as monolayer graphene, no optical second harmonic generation (SHG) is generally expected because it is forbidden under the electric-dipole approx…
Stacking-symmetry governed second harmonic generation in graphene trilayers
Yuwei Shan, Yingguo Li, Di Huang +4
Crystal symmetry plays a central role in governing a wide range of fundamental physical phenomena. One example is the nonlinear optical second harmonic generation (SHG), which requ…
