  • Laminate, method for producing same, and functional element using same
    Patent number: 9045821
    Abstract: Provided is a laminate which includes a transparent conductive film layer that is composed of an oxide thin film mainly composed of titanium oxide and contains an additional element such as niobium, and also contains an anatase phase having more excellent crystallinity and further has high refractive index and low resistivity by forming an optimal buffer layer on the substrate. Also provided are: a semiconductor light emitting element which comprises the laminate; and a functional element such as a solar cell, which includes the laminate.
