UV-light-assisted anodic etching of unintentionally n-typed doped GaN is described. The electrolyte used was a mixture of buffered aqueous solution and ethylene glycol. Etch rates between 2 and 160 nm/min could be achieved. It is postulated that UV light generates electron-hole pairs to aid oxide formation. The detailed mechanism is not clear yet.
