Self-supporting sheets of cuprous oxide were fabricated by thermally oxidiz
ing (Cu --> CuO) copper foils and deoxidizing (CuO --> Cu2O) in a chamber f
illed with O-2 gas with focused infrared light irradiation. This method pro
ved to be good for preparing cuprous oxide sheets with high purity and low
resistivity. (C) 2001 Elsevier Science B.V. All rights reserved.
