Transparent p-type conducting CuScO2+x films

Transparent films of CuScO2+x have been prepared which show p-type electric al conductivity. The temperature dependence of the conductivity indicates s emiconducting behavior with an apparent room temperature activation energy of 0.11 eV. The highest room temperature conductivity observed was 30 S cm( -1). Films 110 nm thick show 40% transparency in most of the visible spectr um and become much more transparent in the infrared spectrum. The p-type be havior was confirmed by the Seebeck effect.
