Metallic Nanoalloys on Vertical GaAs Nanowires: Growth Mechanisms and Shape Control of Ni-GaAs Compounds

Nicolas Mallet, Jonas Müller, Julien Pézard, F. Cristiano et autres

GaAs nanowires are promising candidates for emerging devices in a broad field of applications (e.g., nanoelectronics, photodetection, or photoconversion). These nanostructures benefit greatly from a vertical integration, as it allows for the exhibition of the entire nanowire surface. However, one of the …

Large-scale controlled coupling of single-photon emitters to high-index dielectric nanoantennas by AFM nanoxerography

Mélodie Humbert, Romain Hernandez, Nicolas Mallet, Guilhem Larrieu et autres

Improving the brightness of single-photon sources by means of optically resonant nanoantennas is a major stake for the development of efficient nanodevices for quantum communications. We demonstrate that nanoxerography by atomic force microscopy makes possible the fast, robust and repeatable positioning of …

Tailoring Wavelength- and Emitter-Orientation-Dependent Propagation of Single Photons in Silicon Nanowires

Mélodie Humbert, Peter R. Wiecha, Gérard Colas des Francs, X Yu et autres

Designing the propagation of single quanta at subwavelength scale is of major interest for integrated optical quantum information transfer. This study demonstrates the high potential of crystalline silicon wires with nanometric sections as low-loss nanochannels for quantum nanophotonics. Single photons from N-$V$ …

Hyper-Doped Silicon Nanoantennas and Metasurfaces for Tunable Infrared Plasmonics

Jean‐Marie Poumirol, Clément Majorel, Nicolas Chery, Christian Girard et autres

We present the experimental realization of ordered arrays of hyper-doped silicon nanodisks, which exhibit a localized surface plasmon resonance. The plasmon is widely tunable in a spectral window between 2 and 5 μm by adjusting the free carrier concentration between 10 20 …

(Invited) High Index Dielectric Nanoantennas for Light Management, Controlled Photoluminescence of Quantum Emitters, and Semiconductor-Based Plasmonics

Vincent Paillard, Clément Majorel, Arnaud Arbouet, Caroline Bonafos et autres

Recently, an alternative to plasmonics emerged with high-refractive index dielectric nanostructures (e.g. silicon, n≈4 in the visible range), which offer the same kind of applications as nanostructures of noble metals, but with interesting advantages and despite lower field enhancement and confinement volume. …

Template‐Directed Synthesis of Titania Nanocages with Four Tetrahedrally Arranged Open Windows

Jiaji Cheng, Nicolas Mallet, Walid Baaziz, Ovidiu Ersen et autres

Original titania nanocages are fabricated from sacrificial silica/polystyrene tetrapod-like templates. Here the template synthesis, titania deposition and nanocage development through polystyrene dissolution and subsequent silica etching are described. Discussion about the competitive deposition of titania on the biphasic templates is particularly emphasized. …
