The aim of the present paper is to test the capability of nonstoichiometric CuO as a conductance sensor material. The surface conductivity changes in CuO were measured in the presence of various donor-acceptor couples. The influence of water and oxygen was investigated as well as NO2 and CO. NO2 had a very high sensitivity.Kinetic schemes of surface reactions are also reported and discussed. (C) 2003 Elsevier B.V. All rights reserved.

Abstract
The aim of the present paper is to test the capability of nonstoichiometric CuO as a conductance sensor material. The surface conductivity changes in CuO were measured in the presence of various donor-acceptor couples. The influence of water and oxygen was investigated as well as NO2 and CO. NO2 had a very high sensitivity.Kinetic schemes of surface reactions are also reported and discussed. (C) 2003 Elsevier B.V.
