Abstract	The phase transition process of pure and 0.5 at% Fe-doped 0.95(Na1/2Bi1/2)TiO3-0.05BaTiO(3) (NBBT5) single crystals under in-situ electric-field was investigated using the Raman spectroscopy. The pure NBBT5 exhibited Ric (a(-)a(-)a(-) octahedral tilting) symmetry when subjected to an external electric field (E) up to 70 kV/cm. While after the Fe-doping, the crystal underwent a transition from P4bm (a(0)a(0)c(+) octahedral tilting) to P4mm (a(0)a(0)c(+) octahedral tilting) phase under E of 30-40 kV/cm. The results indicated that the octahedral tilting in the Fe-NBBT5 was substantially suppressed by the electric field, which was suggested to contribute to the enhanced piezoelectric response compared to the pure one.
