METHOD OF NON-CATALYTIC FORMATION AND GROWTH OF NANOWIRES

摘要

PROBLEM TO BE SOLVED: To provide a method for the non-catalytic growth of nanowires.;SOLUTION: The method includes a reaction chamber having an inlet end, an exit end and capable of being heated to an elevated temperature. A carrier gas with a definite flow rate is allowed to enter the reaction chamber through the inlet end and exit the chamber through the exit end. Upon passing through the chamber, the carrier gas comes into contact with a precursor which is heated within the reaction chamber. A collection substrate placed downstream from the precursor allows for the formation and growth of nanowires thereon without the use of a catalyst. A second embodiment comprises the reaction chamber, the carrier gas, a precursor target, a laser beam and the collection substrate. The carrier gas with a definite flow rate and gas pressure is allowed to enter the reaction chamber through the inlet end and exit the reaction chamber through the exit end. The laser beam is focused on the precursor target, which affords for the evaporation of the precursor material and subsequent formation and growth of the nanowires on the collection substrate.;COPYRIGHT: (C)2008,JPO&INPIT
