Nonlinear twistoptics at symmetry-broken interfaces
Kaiyuan Yao, Nathan R. Finney, Jin Zhang +17
Broken symmetries induce strong nonlinear optical responses in materials and at interfaces. Twist angle can give complete control over the presence or lack of inversion symmetry at…
Broadband optical parametric amplification by two-dimensional semiconductors
Chiara Trovatello, Andrea Marini, Xinyi Xu +11
Optical parametric amplification is a second-order nonlinear process whereby an optical signal is amplified by a pump via the generation of an idler field. It is the key ingredient…
One-Dimensional Moiré Excitons in Transition-Metal Dichalcogenide Heterobilayers
Yusong Bai, Lin Zhou, Jue Wang +15
The formation of interfacial moiré patterns from angular and/or lattice mismatch has become a powerful approach to engineer a range of quantum phenomena in van der Waals heterostru…
Direct determination of momentum resolved electron transfer in the photo-excited MoS2/WS2 van der Waals heterobilayer by TR-ARPES
Fang Liu, Qiuyang Li, Xiaoyang Zhu
Photo-induced charge separation in transition metal dichalcogenide heterobilayers is being explored for moiré excitons, spin-valley polarization, and quantum phases of excitons/ele…
Direct Determination of Band Gap Renormalization in Photo-Excited Monolayer MoS2
Fang Liu, Mark Ziffer, Kameron R. Hansen +2
A key feature of monolayer semiconductors, such as transition-metal dichalcogenides, is the poorly screened Coulomb potential, which leads to large exciton binding energy (Eb) and…
