Abstract

We report the preparation of lead magnesium niobate titanate films on a buffered silicon substrate using pulsed laser deposition with double-pulse excitation. A Nd: YAG (355 nm) laser and a KrF (248 nm) excimer laser were combined. The film morphology changed drastically concomitant with the delay time. Suppression of droplets was observed when the Nd:YAG (9.0 × 10 ¹ J.Cm^-2) was used as the first laser and KrF (5.0 × 10^-2 J.cm^-2) was used as the second laser with a 0.5 μs time delay. The fluence of the second laser was responsible for the resultant phase and when the fluence of KrF is 9.5 ×10^-1 J.cm^-2, a significant amount of pyrochlore type compounds coexisted.
