Electrochemical etching of crystalline n-GaN in H2SO4:H2O2 results in the formation of porous GaN. Scanning electron microscopy images revealed the presence of branches on the surface of porous GaN and showed the varying stages with etching time. The branches on the surface of the porous GaN that ha...
