中文摘要
采用溅射法和水热法在衬底上成功地制备了外延生长的压电薄膜。观察到明显的磁滞回线来源于铁电性和压电性。用该压电膜制作的超声换能器发射和接收频率均超过100 MHz,且具有良好的S/N比。
英文摘要
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.
