Identical-length nanowire arrays in anodic alumina templates.
Arrays of nanowires with identical length are fabricated by using ultrasound to remove the length fluctuation among nanowires, which are deliberately grown in burette-shaped nanochannels on an anodic anumina film. The process allows the fabrication of 10 micron Ag-nanowire arrays with length fluctuation as small as 0.09%. By integrating the process with a focused-ion-beam-based lithographic method to grow nanowires into selective nanochannels in an array, we fabricate arrays of uniform-length nanowires that are arranged in a custom-designed lateral geometry. The ability to fabricate such artificial nanomaterials paves the way for the exploitation of their unusual optical, electrical, and thermal properties.
