Abstract

0.85Bi _0.5Na _0.5TiO ₃-0.15Bi _0.5K _0.5TiO ₃ (BNKT15) lead-free thin films were prepared on Pt(111)/TiO ₂/SiO ₂/Si(100) substrates by the chemical solution deposition method. BNKT15 are MPB composition in the Bi _0.5Na _0.5TiO ₃-Bi _0.5K _0.5TiO ₃ (BNT-BKT) system. The maximum piezoelectric coefficient (d _33,f) value of BNKT15 thin film is approximately 75 pm/V, which is comparable to that of polycrystalline PZT thin films. These results suggest that BNKT15 thin film can be used as an alternative for PZT films in piezoelectric micro-electromechanical systems.
