As the dimensionality of materials generally affects their characteristics, thin films composed low-dimensional nanomaterials, such as nanowires (NWs) or nanoplates, are great importance in modern engineering. Among various bottom-up film fabrication strategies, interfacial assembly nanoscale building blocks holds promise constructing large-scale aligned films, leading to emergent enhanced collective properties compared individual blocks. for 1D nanostructures, self-assembly causes morphology orientation, effectively achieving anisotropic electrical, thermal, and optical conduction. However, issues defects between each block, crystal homogeneity constrain application ordered films. The precise control transdimensional synthesis formation mechanism from 2D rarely reported. To meet this gap, we introduce an interfacial-assembly-induced strategy successfully synthesize quasi-2D nanofilms

Abstract Self‐assembled nanoparticle or nanowire networks have recently come under the spotlight as systems able to emulate brain‐like data processing performances by exploiting memristive character and wiring of junctions connecting nanostructured network building blocks. Recently it is demonstrated that Au films, fabricated assembling gold clusters produced in gas phase, non‐linear non‐local electric conduction properties caused extremely high density grain boundaries resulting complex arrangement nanojunctions. These observations suggest metallic films can be explored exploited a novel class neuromorphic for unconventional electronic devices. Here reported cluster‐assembled Pt show resistive switching activity, negative differential resistance, reversible memory effects. allow use programmable analog circuits, such gain amplifiers relaxation oscillators with fast response.
