Tetragonal CuO: A new end member of the 3d transition metal monoxides
Monoclinic CuO is anomalous both structurally as well as electronically in
the 3 transition metal oxide series. All the others have the cubic rock salt
structure. Here we report the synthesis and electronic property determination
of a tetragonal (elongated rock salt) 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 3d transition monoxides, its magnetic properties should be
that of a high antiferromagnet
