β-Ga2O3, with a bandgap of ∼4.6–4.9 eV and readily available bulk substrates, has attracted tremendous interest in the wide semiconductor community. Producing high aspect ratio β-Ga2O3 3D nanostructures without surface damage is crucial for next-generation power electronics. However, most wet etching methods can only achieve very limited ratios, while dry etch usually damages due to energy ions.
