扫描非线性介电显微镜（SNDM）是第一个成功的观察铁电畴分布的纯电学方法。目前其分辨率已达亚纳米量级。作为测量铁电畴的另一种方法，经常使用压电响应成像方法。在本研究中，我们将 SNDM 的分辨率与压电响应成像的分辨率进行比较，并证实 SNDM 的分辨率比压电成像获得的分辨率高得多。还进行了将SNDM系统应用于铁电读写系统的基础研究。
Scanning nonlinear dielectric microscopy (SNDM) is the first successful purely electrical method for observing the ferroelectric domain distributions. At present its resolution is of the sub-nanometer order. As another method for measuring the ferroelectric domains, the piezoelectric response imaging method is often used. In this study, we compare the resolution of SNDM with that of piezoelectric response imaging and confirm that SNDM gives a much higher resolution than that obtained by piezoelectric imaging. A fundamental study to apply the SNDM system to the ferroelectric reading and writing system is also performed.
