“…In previous works [18,27], we already verified the effectiveness and the outlook of this localization approach. The systematic analysis reported here allows to extend this technique to any kind of colloidal nanocrystals (provided that they are soluble in resist blends) with a broad range of concentrations.…”

“…In particular, the incorporation of such NCs in PMMA increases the refractive index of the polymer from 1.49 up to 1.62. The nanocomposite has been used to fabricate a ridge cavity confined by two active blend/air distributed Bragg Reflectors (DBRs) with an e-beam energy of 20 keV and a distributed feedback (DBF) structure formed of periodic corrugations on top of waveguides by a beam energy of 1 keV [ 153 ]. Highly ordered triangular-shaped gold nanopatterns 200 nm in size on PMMA resist modified with CdSe@ZnS NCs and CdSe nanorods, respectively have been fabricated.…”

The unique size- and shape-dependent electronic properties of nanocrystals (NCs) make them extremely attractive as novel structural building blocks for constructing a new generation of innovative materials and solid-state devices. Recent advances in material chemistry has allowed the synthesis of colloidal NCs with a wide range of compositions, with a precise control on size, shape and uniformity as well as specific surface chemistry. By incorporating such nanostructures in polymers, mesoscopic materials can be achieved and their properties engineered by choosing NCs differing in size and/or composition, properly tuning the interaction between NCs and surrounding environment. In this contribution, different approaches will be presented as effective opportunities for conveying colloidal NC properties to nanocomposite materials for micro and nanofabrication. Patterning of such nanocomposites either by conventional lithographic techniques and emerging patterning tools, such as ink jet printing and nanoimprint lithography, will be illustrated, pointing out their technological impact on developing new optoelectronic and sensing devices.

“…In particular, control of self-assembly of functional materials based on dewetting is immensely important for realizing the possibility of adapting processing technologies to fabricate desired patterns over large areas [15][16][17][18][19]. Owing to impressive progress in materials science, a broad range of strategies used to pattern nanoparticles have been designed given rise to a variety of top-down methods such as advanced photolithographic techniques (EBL) [20,21] (soft embossing, decal transfer microlithography (DTM) [22], imprinting [23], soft lithography [24], micro-contact and microtransfer printing [22][23][24][25]. However, elastomeric stamps can contaminate solutions with unreacted oligomers [26] and swell upon contact with nonpolar solvents (e.g., hydrocarbons, toluene, and dichloromethane) [27].…”
