Abstract
This research explores the synthesis of thin zinc oxide (ZnO) layers using electrochemical etching, a fast and cost-effective method for nanostructure fabrication. The study investigates the influence of electrolyte nature, concentration, and anodization voltage on ZnO morphology. Experimental results identified NaOH as the most effective electrolyte, and the anodization potential was optimized through SEM (Scanning Electron Microscopy) analysis to achieve high-quality surface structures.
