Description
All inorganic halide perovskites such as Caesium Lead Bromide (CsPbBr3) have continued to attract interest for optoelectronic and sensing applications, yet reproducible, contaminant free thin film growth routes have remained limited. This study reported the chemical vapour deposition (CVD) synthesis of phase pure CsPbBr3 thin films using a two-zone furnace system and provides a detailed mapping of a stable CVD growth window for this material. Systematic variation of deposition temperatures, precursor loading and other growth dynamics established a previously unreported regime that yields compact stoichiometric films. Structural and optical characterization revealed clear structure–property relationships, including grain morphology transitions, octahedral orientation-linked optical signatures, and thermally driven spectral behaviour indicative of reduced defect densities. Preliminary electrical measurements further indicated enhanced carrier transport under optimized conditions. Building on this newly defined CVD platform, current and future efforts will investigate high power plasma treatments, controlled ozone exposure, and targeted post growth annealing strategies to tailor surface chemistry, defect landscapes, and interfacial energetics to enable heterostructure engineering for next generation optoelectronic architectures.
