“…Nowadays, plasmonic nanoparticles can be produced in many different ways including chemical synthesis from precursors and direct fabrication on surfaces through either growth in some cases followed by etching, self‐assembly, or top‐down fabrication methods. Nanoparticle preparation through chemical synthesis is extremely versatile in terms of both materials (metals, plasmonic oxides, etc.)…”

“…The direct deposition of nanoparticles on surfaces by oblique angle deposition or pulsed laser deposition fails to fully control the arrangement of the grown nano‐objects. Although an impressive control of arrangement of nanowires on any substrate can be achieved through electrodeposition with sine‐shaped oscillatory voltage followed by ion etching, only 1D structures can be fabricated.…”

Periodic arrays of anisotropic silver nanoparticles having peculiar optical properties are fabricated at a macroscopic scale. The proposed scalable method is based on temperature-assisted solid-state dewetting of a continuous thin layer deposited on a silica substrate patterned by the nano imprint technique. The resulting nanoparticles are shaped like diamonds and are half-embedded into the patterned silica. A period-dependent optimum in film thickness for the quality of spatial organization is found and discussed in terms of thermodynamics and, for the first time, in terms of the role of grains in the dewetting process. The optical properties of the arrays are driven by not only simply the particle shape but also the lattice period and the degree of order. A surface lattice resonance that disperses with the underlying period is evidenced experimentally and confirmed by optical simulations. The opportunity to fabricate and tune such an assembly of plasmonic particles on transparent substrate opens interesting perspectives for not only fundamental photonics but also potential optical applications.

“…The commendable tunability for their plasmonic behaviors was easily realized by tailoring nanorod dimensions (i.e., length and diameter), separations between nanorods, and dielectric environments. Currently, from the cost and output point of view, electrochemical deposition method is very popular to fabricate self-organized nanostructures, [20][21][22][23][24] especially for the AAO template-assisted cases. [3,18] For instance, Au nanorods/Al 2 O 3 metamaterial fabricated based on porous anodic aluminum oxide (AAO) template, can exhibit ultrafast optical nonlinearity with a response time of ≈1.13 ps, [18] and the relevant nonlinear gain is believed to be dependent on the delocalized longitudinal (L mode) plasmon resonance.…”

Currently, the limitations of conventional methods for fabricating metamaterials composed of well-aligned nanoscale inclusions either lack the necessary freedom to tune the structural geometry or are difficult for large-area synthesis. In this Communication, the authors propose a fabrication route to create well-ordered silver nano forest/ceramic composite single-layer or multi-layer vertically stacked structures, as a distinctive approach to make large-area nanoscale metamaterials. To take advantage of direct growth, the authors fabricate single-layer nanocomposite films with a well-defined sub-5 nm interwire gap and an average nanowire diameter of ≈3 nm. Further, artificially constructed multilayer metamaterial films are easily fabricated by vertical integration of different single-layer metamaterial films. Based upon the thermodynamics as well as thin film growth dynamics theory, the growth mechanism is presented to elucidate the formation of such structure. Intriguing steady and transient optical properties in these assemblies are demonstrated, owing to their nanoscale structural anisotropy. The studies suggest that the self-organized nanocomposites provide an extensible material platform to manipulate optical response in the region of sub-5 nm scale.

“…From an electronic application perspective, a high‐resolution array increases the overall packing density of patterned features, which is critical for miniaturizing semiconductor devices for future applications. Previous studies have shown that the construction of 3D patterned arrays significantly increases the degree of integration, which eventually leads to shorter information access times in microelectronics and spintronics . From a chemical application point of view, the fabrication of carefully designed periodic patterns with a high aspect ratio is desirable for microscale energy‐storage devices with high capacity and rate performance (one application in which these would be required is wearable devices) .…”

The development of high resolution, high aspect ratio metal dichalcogenide nanostructures is one of the most important issues in 2D material researchers due to the potential to exploit their properties into high performance devices. In this study, for the first time a way of fabricating metal dichalcogenide nanostructures with high resolution (<50 nm scale) and high aspect ratios (>120) by chemical vapor deposition assisted secondary sputtering phenomenon is reported. This approach can universally synthesize various types of metal dichalcogenides including MoS 2 , WS 2 , and SnS 2 , implying the possibility for further utilization with selenides and tellurides. Also, this method can produce highly periodic complex patterns such as hole-cylinder, concentric rings, and line patterns, which are unprecedented in previous reports. The feature size and aspect ratio of the metal dichalcogenide structures can be manipulated by controlling the dimensions of the photoresist prepatterns, while the pattern resolution and layer orientation can be manipulated by controlling the thickness of the deposited metal film. It is demonstrated that nanostructures with high resolution and high aspect ratio significantly improve gas-sensing properties compared with previous metal dichalcogenide films. It is believed that the method can be a foundation for synthesizing various materials with complex patterns for future applications.
