介绍了利用扫描非线性介电显微镜(SNDM)测量纳米级铁电畴的理论和实验研究。我们计算了180°c-c区域边界的一维图像，表明SNDM在理论上具有原子尺度的分辨率。实验结果表明，我们测量了宽度为1.5 nm的锆钛酸铅(PZT)薄膜的c-c域，显微镜的分辨率小于0.5 nm。
We describe theoretical and experimental studies for nano-scale ferroelectric domain measurements using scanning nonlinear dielectric microscopy (SNDM). We calculate one-dimensional images of a 180° c-c domain boundary and show that SNDM has an atomic-scale resolution theoretically. Experimental results show that we measure the c-c domain on the lead zirconate titanate (PZT) thin film with the width of 1.5 nm and that the resolution of the microscope is less than 0.5 nm.
