Selectively enhanced microarea crystal growth of ZnO nano- and microwires on GaN on sapphire substrates by mist chemical vapor deposition

The selectively enhanced micro area crystal growth of ZnO nano- and microwires on GaN sapphire substrates by mist chemical vapor deposition (mist-CVD) was demonstrated. Micropatterns a thin Au layer were formed the surface simple technique. with high rates grown micropatterned layer, resulting in microarea growth. lengths some more than 15 µm for 30 min
