Abstract

The current work demonstrates the growth of aluminum-doped ZnO (AZO) hexagonal rods vertically aligned on soda-lime glass (SLG) via the chemical bath deposition (CBD) method. The controlling crystalline orientation was performed using hydrogen peroxide (H2O2) accompanied by C6H17N3O7 as growth controlling agents (CAs). The results showed that the presence of H2O2 significantly promoted (002) plane orientation and significantly improved structural, morphological, and optical properties of AZO. The as-fabricated AZO with H2O2 exhibited a layer thickness of 1.8 μm, optical transparency of 90.4 %, sheet resistivity of 10 Ω □-1, and the resistivity of 1.8 ×10^(-3) Ω.cm. This approach provides an efficient route to alter the AZO morphology and properties for advanced optoelectronic applications.
