Patent

CA 2625647

A method of forming a nanowire is disclosed. In one embodiment, a primary preform is formed comprising at least one central region and a support structure. The primary preform is then drawn to a cane, which is then inserted into an outer portion, to form a secondary preform. The secondary preform is then drawn until the at least one central portion is a nanowire. The method can produce nanowires of far greater length than existing methods, and can reduce the likelihood of damaging the nanowire when handling.

L'invention concerne un procédé de formation d'un nanofil. Dans un mode de réalisation, une préforme primaire comprenant au moins une région centrale et une structure de support est formée. La préforme primaire est ensuite étirée en une tige, qui est ensuite insérée dans une partie externe, pour former une préforme secondaire. La préforme secondaire est ensuite étirée jusqu'à ce que l~au moins une partie centrale soit un nanofil. Le procédé peut produire des nanofils de longueur beaucoup plus importante que des procédés existants, et peut réduire la probabilité de détérioration du nanofil lors d'une manipulation.
