Abstract: Methods of forming films of aligned elongated nanoparticles, films made using the methods, and electronic devices, such as transistors, that incorporate the films are provided. In the methods, elongated nanoparticles floating at the surface of a liquid film are deposited onto a liquid film-adsorbing surface region of a substrate as the liquid film dissipates from the surface. The alignment and deposition of the elongated nanoparticles occurs along a contact line that is defined by the liquid film, the substrate, and either an immiscible liquid suspension of the elongated nanoparticles or air. As the liquid film dissipates, the contact line recedes across the liquid film-adsorbing surface region and elongated nanoparticles pinned at the contact line are deposited onto the surface in the form of a nanoparticle film.
