Document Type and Number:
WIPO Patent Application WO/2023/080173
Kind Code:
A1
Abstract:
The present invention provides a diamond laminate which has excellent electron emission ability and is capable of forming an electrode reaction field that has excellent reductiveness. A laminate according to the present disclosure comprises: an electron excitation layer (1) that has a diamond crystal structure in which some carbon atoms are substituted by nitrogen atoms; and a conductive layer (2) that has a diamond crystal structure in which some carbon atoms are substituted by boron atoms. It is preferable that the nitrogen atom concentration in the layer (1) is 5 × 1018 atoms/cm3 or more; and it is preferable that the boron atom concentration in the layer (2) is 1 × 1019 atoms/cm3 or more. It is preferable that the thickness of the layer (1) is 1 nm to 100 µm; and it is preferable that the thickness of the layer (2) is 1 µm or more.
