  • Abstract
    N-type GaN films grown by Hydride Vapor Phase Epitaxy technique were etched under different conditions at room temperature. Direct evidence of etch-stop effect of dislocations during photoelectrochemical (PEC) etching has been found. Further investigation of the mechanism has been discussed.
