Problems solved by technology

The dielectric / metal / dielectric multilayer structures reported so far all use inorganic semiconductor materials as the dielectric layer. However, due to the influence of the preparation process of the inorganic semiconductor dielectric layer and the properties of the film, the dielectric / metal / dielectric multilayer based on the inorganic semiconductor material is transparent and conductive. The film cannot form good interfacial contact with certain substrates or device active layers, limiting the application of this type of transparent conductive film
