Conductive transparent copper-doped nickel oxide film and preparation method thereof

Abstract

The invention belongs to the field of transparent electronics study and in particular relates to a p-type conductive transparent copper-doped nickel oxide film and a preparation method thereof. The invention provides a p-type conductive transparent oxide semiconductor film, wherein the film is a copper-doped nickel oxide film with chemical formula being Ni1-xCuxO; and x is more than 0 and not more than 0.3. The preparation method is characterized by taking the common glass as the substrate and utilizing the Ni1-xCuxO ceramic target to prepare the film through the pulsed plasma deposition technology under the conditions of proper substrate temperature, oxygen pressure, pulse current and pulse voltage. The prepared film has such excellent photoelectric properties as high conductivity, high transmissivity in the visible light range and the like. Meanwhile, the preparation method has the advantages of simpleness and convenience in operation and relatively low equipment price. Therefore, the novel film material and the preparation method have certain application potentials in the field of semiconductor optoelectronics.

Description

technical field [0001] The invention belongs to the research field of transparent electronics, and in particular relates to a p-type conductive transparent copper-doped nickel oxide film and a preparation method thereof. Background technique [0002] So far, the transparent oxide semiconductor (TransparentOxideSemiconductor, TOS) materials with continuously improved performance are all n-type semiconductors, and the corresponding p-type materials have not made significant progress, so it is impossible to synthesize high-quality transparent oxide pn Junction, which limits the application of TOS materials in the field of semiconductor optoelectronic devices. The p-type transparent oxide semiconductor has become the bottleneck material for the development of transparent electronics, and further research is needed in terms of material selection, conduction mechanism and synthesis process. [0003] NiO is a wide bandgap p-type semiconductor material, and its conductivity at room...
