Abstract

Official abstract text for this publication.

A method for producing a transparent electrode for oxygen production having a Ta nitride layer on a transparent substrate, including: a step of forming a Ta nitride precursor layer on the transparent substrate; and a step of nitriding the Ta nitride precursor layer with a mixed gas containing ammonia and a carrier gas.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a transparent electrode for oxygen production comprising a Ta nitride layer on a transparent substrate, comprising: forming a Ta nitride precursor layer comprising Tantalum on the transparent substrate; and nitriding the Ta nitride precursor layer with a mixed gas comprising ammonia and nitrogen gas, wherein a volume ratio of ammonia and nitrogen in the mixed gas is from 15:85 to 70:30. 2. The production method according to claim 1 , wherein the Ta nitride layer is a Ta 3 N 5 layer. 3. The production method according to claim 1 , wherein the transparent substrate is a sapphire substrate or a SiO 2 substrate. 4. The production method according to claim 1 , wherein a volume ratio of ammonia and nitrogen in the mixed gas is from 20:80 to 50:50.
