“…For film-substrate systems showing this tendency, the plot of the system-free-energy versus the film thickness shows a very similar behaviour to the composition-dependent behavior in two-phases systems characterized by spinodal phase segregation (Figure 16) [37]. Thus, such systems are, often, referred to dewet by spinodal dewetting [37,78,79]. The total free energy of a substrate-film system can be expressed as [37] G(d) = G surf + G int + G vol + G ext , which is dependent on the thickness d of the film.…”

Metal nanostructures are, nowadays, extensively used in applications such as catalysis, electronics, sensing, optoelectronics and others. These applications require the possibility to design and fabricate metal nanostructures directly on functional substrates, with specifically controlled shapes, sizes, structures and reduced costs. A promising route towards the controlled fabrication of surface-supported metal nanostructures is the processing of substrate-deposited thin metal films by fast and ultrafast pulsed lasers. In fact, the processes occurring for laser-irradiated metal films (melting, ablation, deformation) can be exploited and controlled on the nanoscale to produce metal nanostructures with the desired shape, size, and surface order. The present paper aims to overview the results concerning the use of fast and ultrafast laser-based fabrication methodologies to obtain metal nanostructures on surfaces from the processing of deposited metal films. The paper aims to focus on the correlation between the process parameter, physical parameters and the morphological/structural properties of the obtained nanostructures. We begin with a review of the basic concepts on the laser-metal films interaction to clarify the main laser, metal film, and substrate parameters governing the metal film evolution under the laser irradiation. The review then aims to provide a comprehensive schematization of some notable classes of metal nanostructures which can be fabricated and establishes general frameworks connecting the processes parameters to the characteristics of the nanostructures. To simplify the discussion, the laser types under considerations are classified into three classes on the basis of the range of the pulse duration: nanosecond-, picosecond-, femtosecond-pulsed lasers. These lasers induce different structuring mechanisms for an irradiated metal film. By discussing these mechanisms, the basic formation processes of micro- and nano-structures is illustrated and justified. A short discussion on the notable applications for the produced metal nanostructures is carried out so as to outline the strengths of the laser-based fabrication processes. Finally, the review shows the innovative contributions that can be proposed in this research field by illustrating the challenges and perspectives.

“…Periodical nanostructures as small as 50 nm have been obtained through similar pulse laser irradiations in various liquids [5,8,9]. These unique structures have many applications, such as field emission, gas sensing, and surface enhancement Raman sensing [8,10,11,12,13]. This method can form submicron structures or nanostructures that are much lower than the laser wavelength.…”

“…Moreover, it can cause the solid surface to melt, and the re-solidification of the molten surface can leave interesting patterns on the surface. Micro-hole arrays on various metals have been obtained under tightly focused femtosecond laser pulses [13,16]. Patterns of strips, islands, or spikes with very uniform periodicity have been found on silicon surfaces after femtosecond laser irradiations [4,5].…”

“…Other than the vaporized or escaped species, the patterns left on sample surface attract our interests because of their regularity in nanoscale and convenience for applications in making devices. Explanations using laser profiles, thermal properties of materials, solidification of capillary waves, photon diffractions, and plasmonic effect have been previously introduced to understand the formation of these patterns [13,16,19,20,21,22,23]. Straight ripples with uniform periodicity have been generated on different material surfaces by using a linearly polarized laser beam, and diffraction mechanism was successfully implemented to explain the formation of these structures [8,24,25].…”

Femtosecond Laser-Induced Thermal Transport in Silicon with Liquid Cooling Bath

et al. 2019

Nanostructured regular patterns on silicon surface are made by using femtosecond laser irradiations. This is a novel method that can modify the surface morphology of any large material in an easy, fast, and low-cost way. We irradiate a solid surface with a 400-nm double frequency beam from an 800-nm femtosecond laser, while the solid surface is submerged in a liquid or exposed in air. From the study of multiple-pulses and single-pulse irradiations on silicon, we find the morphologies of nanospikes and capillary waves to follow the same distribution and periodicity. Thermal transport near the solid surface plays an important role in the formation of patterns; a simulation was done to fully understand the mechanism of the pattern formation in single pulse irradiation. The theoretical models include a femtosecond laser pulse function, a two-temperature model (2-T model), and an estimation of interface thermal coupling. The evolution of lattice temperature over time will be calculated first without liquid cooling and then with liquid cooling, which has not been well considered in previous theoretical papers. The lifetime of the capillary wave is found to be longer than the solidification time of the molten silicon only when water cooling is introduced. This allows the capillary wave to be frozen and leaves interesting concentric rings on the silicon surface. The regular nanospikes generated on the silicon surface result from the overlapping capillary waves.

Metalenses (MLs), representing a groundbreaking paradigm shift within the realm of optics, have ushered in a transformative era in the ability to manipulate and harness the power of light. Diverging from the conventional approach reliant on curved surfaces to bend light, MLs harness intricate arrays of minuscule nanostructures to exert precise control over the phase and amplitude of incident light waves. This revolutionary technology bestows a plethora of advantages, including the creation of ultra‐compact optical systems, the enhancement of focusing capabilities to unprecedented levels, and the capability to rectify optical aberrations in a significantly thinner and more lightweight form factor. MLs have discovered a multitude of applications spanning diverse fields, from imaging and photography to augmenting reality and refining medical devices. They stand as a beacon of hope for reshaping the landscape of optical systems, courtesy of their remarkable adaptability and exceptional performance. As the evolution of MLs forges ahead, they hold immense potential to transcend the boundaries of what can be accomplished in the domain of light‐based technologies. This review presents the recent advances in reconfigurable MLs and their applicability to imaging systems.
