| Abstract Scope |
Chemical bath deposition (CBD) is a simple and effective method where a sample is submerged in a reactive precursor solution under ambient conditions with moderate heating to produce conformal films. In this study, CBD approaches for zinc oxide (ZnO) are explored, specifically for sensor devices such as photodetectors and electromechanical transducers. A custom high-throughput chemical bath deposition (HT-CBD) technique is demonstrated, enabling rapid process optimization through parametric studies of formulation and reaction conditions. Using HT-CBD, variables such as ZnO precursor material, surface treatment, substrate, concentration, reaction temperature, and modifying agents (e.g., capping agents and secondary solvents) are systematically tested and characterized. Characterization methods include X-ray diffraction, scanning electron microscopy, sessile drop goniometry, and electrical performance testing. |
