Abstract

Abstract:

We investigated the ordered assembly of Te nanowires under the assistance of agitation and prepared several nanowires arrays through in situ chemical reaction of the assembled Te nanowires. The Te nanowires with long aspect ratio were synthesized through hydrothermal method and then were aligned on the substrate of quartz by agitation-assisted assembly. The influences of the sides of the substrate, solvent, stirring rate and concentration on the morphology of the assembled nanowires were studied. Using the orientated Te nanowires as templates, the arrays of Pt, Pd and Ag₂Te nanowires were fabricated by in situ chemical conversion. Due to the distinct properties of the above nanowires, the prepared arrays would be of great potential in the fields of sensor and photoelectronic device. This study indicates the capability of the agitation-assisted assembly in the fabrication of nanowires array, offering a new approach to obtain two-dimension ordered structure.

Key words: Surface assembly, Nanowires alignment, Agitation, Te nanowires
