Abstract
Monoclinic CuO is anomalous both structurally as well as electronically in the transition metal oxide series. All the others have the cubic rocksalt structure. Here we report the synthesis and electronic property determination of a tetragonal (elongated rocksalt) form of CuO created using an epitaxial thin-film deposition approach. In situ photoelectron spectroscopy suggests an enhanced charge-transfer gap with the overall bonding more ionic. As an end member of the transition monoxides, its magnetic properties should be that of a high antiferromagnet.

How to make CuO sit up straight
Published 8 June 2009
in thin-film form could be a prototype material for exploring magnetism that is similar to what is found in high-temperature superconductors.
