Initial talk with transfer of knowledge of the ER to the host group about: Nanoscale fabrication methods with high resolution and yielding large area patterns have been a prominent research area in the recent years due to its crucial role in the implementation of nanosized devices in various applications. Soft nanoimprinting lithography is an easy and scalable fabrication technique that allows seamless integration of photonic nanostructures in many optoelectronic fabrication procedures. In this talk, we will discuss the response of these metasurfaces that have been fabricated using soft nanoimprinting. These photonic architectures are exceptionally interesting due to their ability to support strong collective lattice resonances arising from the coherent multiple scattering enabled by the array periodicity. Thanks to these exceptional properties, periodic arrays can be exploited in a wide variety of applications, including ultrasensitive biosensing, nanoscale light emission, and broadband absorption.

Like graphite, transition metal dichalcogenide (TMDC) bulk crystals are formed of monolayers bound to each other by van-der-Waals attraction. TMDC monolayers have a direct band gap, and can be used in electronics as transistors and in optics as emitters and detectors. However, thickness-limited absorption poses a challenge for high efficiency. To overcome this issue, light-trapping techniques such as patterning is suggested. The possibility of direct writing structures with a laser on insulating substrates in a clean room-free process is attractive for its simplicity, cost effectiveness and wide choice of substrates allowed, including flexible plastic.

Two dimensional materials have emerged as a toolbox for nanophotonics and nanooptoelectronics providing new properties that are not possible in conventional materials. In particular semiconductor transition metal dichalcogenides (TMDC) show unique optical properties. In this work we propose a nanostructure based on TMDC which achieves extraordinary transmission through a continuous thin metallic film.

We developed a nanostructure to enhance the photoluminescence intensity of two-dimensional monolayers of transition metal dichalcogenides based on plasmonic supercrystal arrays. These plasmonic supercrystal arrays are deposited on top the monolayers by means of a template-assisted assembly of gold nanospheres with patterned polydimethylsiloxane molds [1]. These supercrystals arrays consist on square arrays of hexagonally packed gold nanoparticles (50 nm of diameter) which exhibit well-defined surface lattice resonance modes that can be tuned from the visible through the near-infrared by simple variation of the lattice parameter. This tunability can be used to enhance the photoluminescence emission of different transition metal dichalcogenides monolayers. So, as proof of concept, the photoluminescence signal of the monolayer MoS2 and MoSe2 can be significantly enhanced up to 5-6-fold coupling the frequency of the surface lattice resonance of the plasmonic supercrystal to the frequency emission of the transition metal dichalcogenides monolayer.
