| Research Abstract |
The epitaxially-grown piezoelectric films were successfully obtained on the substrates by the spattering method and hydrothermal method. The clear hysteresis loops originated from the ferroelectricity and the piezoelectricity were observed. Moreover, fabricated ultrasonic transducer with the developed piezoelectric films was able to the ultrasonic transmit and receive over 100MHz with good S/N.
