Abstract

A well-aligned Cu₂O nanowire array was fabricated by the stress-induced method. A new stress-redistribution phenomenon related to the cooling procedure was observed and a creative growth procedure was demonstrated. High-quality Cu₂O nanowires with an aspect ratio up to 300 and a growth density higher than 10⁹ cm^-2 can be derived under the optimum condition of cooling gradually for 4 h after heating for 5 h. A typical photovoltaic effect was demonstrated to exist in the Cu₂O/Cu junction.
