Abstract

TiO₂-rich Ba-Ti-O films were prepared on Pt/Ti/SiO₂/Si substrate by laser chemical vapor deposition (LCVD). Their phase relationship and microstructure were investigated. The single-phase BaTi₂O₅, Ba₄Ti₁₃O₃₀ and BaTi₅O₁₁ films were prepared at Ti/Ba molar ratios m_Ti/Ba = 1.84–1.90, 2.83 and 4.49–4.55, respectively. The high deposition rate of TiO₂-rich Ba-Ti-O films ranged from 54.0 μm/h to 177.6 μm/h. The permittivity of BaTi₂O₅ film (prepared at m_Ti/Ba = 1.84 and deposition temperature T_dep = 877 K), Ba₄Ti₁₃O₃₀ film (prepared at m_Ti/Ba = 2.83 and T_dep = 914 K) and BaTi₅O₁₁ film (prepared at m_Ti/Ba = 4.49 and T_dep = 955 K) were 50, 40 and 21, respectively.
