摘要：
Relaxor ferroelectric Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) thin films were epitaxially grown on (001)-oriented SrTiO3 buffered III-V semiconductor GaAs substrates by pulsed laser deposition. Detailed microstructural investigations of the films were carried out using X-ray diffraction, atomic force microscopy and transmission electron microscopy. Local piezoresponse force microscopy hysteresis loops confirm the ferroelectric nature of the PMN-PT thin films on GaAs. The results have demonstrated the practicality of integrating epitaxial PMN-PT films on semiconductor GaAs, which may pave the way to develop III-V semiconductor based opto-mechanical devices.
