Metal-assisted photochemical etching of GaN nanowires: The role of metal distribution

Electrochemistry Communications, 2019
Metal-assisted chemical etching plays a critical role in synthesizing GaN nanowires. In this work, GaN films grown on Si(111) substrates are immersed in CuSO4/HF etchant under UV illumination to fabricate nanowires.
