Abstract

We propose a new nitride photocatalyst of an n-n⁺-GaN structure to increase H₂ gas generation. This structure consists of a thin lightly-doped n-type layer on a heavily-doped n⁺-type layer to realize an optimized depletion layer for optical absorption and highly conductive region, respectively. An optimized n-n⁺-GaN structure could generate much more H₂ gas rather than a single n-GaN layer structure by about 1.4 times.
