Improved photoelectrochemical performance of GaN nanopillar photoanodes [PDF]

Nanotechnology, 2017
Abstract In this work, we report on the photoelectrochemical (PEC) investigation of n-GaN nanopillar (NP) photoanodes fabricated using metal organic chemical vapour deposition and the top-down approach. Substantial improvement in photocurrents is observed for GaN NP photoanodes compared to their planar counterparts.
