Journal ArticleDOI
Anapoles in Free-Standing III–V Nanodisks Enhancing Second-Harmonic Generation
Maria Timofeeva,Lukas Lang,Flavia Timpu,Claude Renaut,A.D. Bouravleuv,Igor Shtrom,G. E. Cirlin,Rachel Grange +7 more
TL;DR: This work presents a new design of free-standing disk nanoantennas with nonradiating current distributions for the optical near-infrared range and shows a novel approach to creating nanoantENNas by slicing III-V nanowires into standing disks using focused ion-beam milling.
Journal ArticleDOI
Second-Harmonic Enhancement with Mie Resonances in Perovskite Nanoparticles
TL;DR: In this article, the intrinsic scattering properties of an all-dielectric perovskite nanostructure were used to enhance the second-harmonic generation (SHG) signal at the nanoscale.
Journal ArticleDOI
Enhanced Second-Harmonic Generation from Sequential Capillarity-Assisted Particle Assembly of Hybrid Nanodimers.
Flavia Timpu,Nicholas R. Hendricks,Mihail Petrov,Songbo Ni,Claude Renaut,Heiko Wolf,Lucio Isa,Yuri S. Kivshar,Yuri S. Kivshar,Rachel Grange +9 more
TL;DR: Enhanced second-harmonic generation (SHG) from a hybrid metal-dielectric nanodimer consisting of an inorganic perovskite nanoparticle of barium titanate coupled to a metallic gold (Au) nanoparticle is shown.
Journal ArticleDOI
Lithium Niobate Nanocubes as Linear and Nonlinear Ultraviolet Mie Resonators
Flavia Timpu,Joan Sendra,Claude Renaut,Lukas Lang,Maria Timofeeva,Maria Teresa Buscaglia,Vincenzo Buscaglia,Rachel Grange +7 more
TL;DR: Many dielectric and semiconductor materials used for all-dielectric resonators or metasurfaces have low absorption in the near-infrared to visible range, but they are lossy in near-ultraviolet range as mentioned in this paper.
Journal ArticleDOI
Tunable 2D Binary Colloidal Alloys for Soft Nanotemplating
Miguel Angel Fernandez-Rodriguez,Roey Elnathan,Ran Ditcovski,Fabio Grillo,Gaurasundar M. Conley,Flavia Timpu,Astrid Rauh,Karen Geisel,Tal Ellenbogen,Rachel Grange,Frank Scheffold,Matthias Karg,Walter Richtering,Nicolas H. Voelcker,Nicolas H. Voelcker,Nicolas H. Voelcker,Lucio Isa +16 more
TL;DR: It is shown that microgel particles can for instance be transferred to silicon substrates, where they act as masks for the metal-assisted chemical etching of binary arrays of vertically aligned silicon nanowires (VA-SiNWs) with fine geometrical control.
