This investigation revealed the ZnO (E_g =3.37 eV) growth mechanism for solution-dependent electrostatic spray deposition (ESD) [1]. For making the ESD spray solutions, zinc chloride (ZnCl₂) was used with ethanol (CH₃CH₂OH) for preparing the six different 0.1 M precursor solutions by changing the Hydrochloric acid (HCl) and water (H₂O) ratio. Numerous microstructure parameters were also studied. by ESD during ZnO thin film formation.
