By combination of plasmonic nanostructures with 1L-WS2 by transferring it onto a plasmonic nanoantenna array, a hybrid metasurface is realized impacting the polarization dependency of its SHG. Here, we investigate how plasmonic dipole resonances affect the process of SHG in plasmonic–TMD hybrid metasurfaces by nonlinear spectroscopy. We show that the polarization dependency is affected by the lattice structure of plasmonic nanoantenna arrays as well as by the relative orientation between the 1L-WS2 and the individual plasmonic nanoantennas. In addition, such hybrid metasurfaces show SHG in polarization states, where SHG is usually forbidden for either 1L-WS2 or plasmonic nanoantennas. By comparing the SHG in these channels with the SHG generated by the hybrid metasurface components, we detect an enhancement of the SHG signal by a factor of more than 40. Meanwhile, an attenuation of the SHG signal in usually allowed polarization states is observed. Our study provides valuable insight into hybrid systems where symmetries strongly affect the SHG and enable tailored SHG in 1L-WS2 for future applications.","lang":"eng"}],"publication":"ACS Nano","language":[{"iso":"eng"}],"year":"2021","quality_controlled":"1","issue":"10","title":"Influence of Plasmon Resonances and Symmetry Effects on Second Harmonic Generation in WS2–Plasmonic Hybrid Metasurfaces","date_created":"2021-10-07T07:39:27Z","status":"public","type":"journal_article","article_type":"original","funded_apc":"1","project":[{"_id":"53","name":"TRR 142"},{"_id":"54","name":"TRR 142 - Project Area A"},{"name":"TRR 142 - Subproject A7","_id":"64"},{"_id":"65","name":"TRR 142 - Subproject A8"}],"_id":"25605","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"}],"citation":{"apa":"Spreyer, F., Ruppert, C., Georgi, P., &#38; Zentgraf, T.

However, the underlying collision dynamics behind solid HHG is still intensively debated and no direct mapping relationship between the collision dynamics with band structure has been built. Here, we show that the electron and its associated hole can be elastically scattered by neighboring atoms when their wavelength approaches the atomic size. We reveal that the elastic scattering of electron/hole from neighboring atoms can dramatically influence the electron recombination with its left-behind hole, which turns out to be the fundamental reason for the anisotropic interband HHG observed recently in bulk crystals. Our findings link the electron/hole backward scattering with Van Hove singularities and forward scattering with critical lines in the band structure and thus build a clear mapping between the band structure and the harmonic spectrum. Our work provides a unifying picture for several seemingly unrelated experimental observations and theoretical predictions, including the anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding will pave the way for controlling the solid-state HHG and visualizing the structure-dependent electron dynamics in solids.</jats:p>"}],"user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"35"}],"project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142: TRR 142"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"_id":"64","name":"TRR 142 - A7: TRR 142 - Subproject A7"}],"_id":"37331","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2765-8791"]},"citation":{"ieee":"R.

Femtosecond photoexcitation leads to very substantial transmission changes in a ∼10-meV broad spectral range within the transparency window of the unexcited semiconductor. These nonlinear optical signatures decay on picosecond time scales governed by carrier thermalization and recombination. The temporal and spectral dependence indicate the dynamical optical response as arising from excitation-induced dephasing and perturbed free induction decay. Model simulations for the optical response taking into account the actual exciton-polariton dispersion and excitation-induced dephasing of a nonlinearly driven two-level system support this interpretation.","lang":"eng"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"429"}],"user_id":"49063","_id":"13920","project":[{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A2","_id":"59"},{"_id":"64","name":"TRR 142 - Subproject A7"},{"name":"TRR 142 - Project Area C","_id":"56"},{"_id":"72","name":"TRR 142 - Subproject C2"},{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"funded_apc":"1","language":[{"iso":"eng"}]},{"publication_status":"published","publication_identifier":{"issn":["2045-2322"]},"citation":{"ieee":"X.
