    摘要: Techniques for making nanowires with a desired diameter are provided. The nanowires can be grown from catalytic nanoparticles, wherein the nanowires can have substantially same diameter as the catalytic nanoparticles. Since the size or the diameter of the catalytic nanoparticles can be controlled in production of the nanoparticles, the diameter of the nanowires can be subsequently controlled as well. The catalytic nanoparticles are melted and provided with a gaseous precursor of the nanowires. When supersaturation of the catalytic nanoparticles with the gaseous precursor is reached, the gaseous precursor starts to solidify and form nanowires. The nanowires are separate from each other and not bind with each other to form a plurality of nanowires having the substantially uniform diameter.

    摘要: A novel method of transporting ink to a substrate with dip-pen nanolithographic (DPN) stamp tips coated with polymer (e.g., polydimethylsiloxane (PDMS), etc.). This kind of tip adsorbs chemicals (“inks”) easily and is used to generate DPN nanopatterns that are imaged with the same tip after a DPN process. This method builds a bridge between micro-contact printing (μCP) and DPN, making it possible for one to easily generate smaller structures of any molecules that have been patterned by the μCP technique. The easy tip-coating and writing process enriches the state-of-the-art DPN technique. The sub-100 nm DPN resolution obtained by using this kind of novel tip is comparable to that with a conventional Si3N4 probe tip. Importantly, the unique stamp tip was able to transfer solvent (e.g., liquid “ink”) onto a substrate, resulting in fabrication of hollow nanostructures with only one DPN holding/writing step. Inks comprising metals and sol-gel materials are noted, as well as applications in photomask repair, enhancement, and fabrication.
