Patent ID: 8242000

Claim:
A method for making a nanowire element, comprising steps of: providing an imprint mold, the imprint mold comprising a first substrate and a conductive pattern-transferring layer formed on the first substrate, the conductive pattern-transferring layer comprising a plurality of first conductive strips spaced from each other; electrifying the conductive pattern-transferring layer with an alternating current; applying a nanowire-containing suspension on the conductive pattern-transferring layer, the nanowire-containing suspension containing a plurality of nanowires; reorienting the nanowires using a dielectrophoresis method, thereby the nanowires connected between two adjacent first conductive strips; providing a pattern-receiving body, the pattern-receiving body comprising a second substrate and a pattern-receiving layer formed on the second substrate; pressing the imprint mold onto the pattern-receiving body with the conductive pattern-transferring layer facing the pattern-receiving layer, thereby defining a patterned recess in the pattern-receiving layer and transferring the nanowires to the second substrate; forming a first conductive layer on the second substrate to obtain a conductive pattern layer in the pattern-receiving layer, the conductive pattern layer comprising a plurality of second conductive strips spaced from each other, the nanowires connecting two adjacent second conductive strips; and removing the pattern-receiving layer.
