Examples
- Nonlinear dielectric properties of pt p0 - 3 ferroelectric composite materials
复合物的非线性介电性质 - Performance simulation of nonlinear dielectric under ac condition
非线性电介质交流激励下响应特性仿真 - The natures of the probe and formation mechanisms in these techniques are different ; therefore , the images of spm can reflect different properties of sample surface . in this work , related properties of ferroelectric thin film were investigated as followed : the main factors determining the image formation of piezoresponse force microscopy ( pfm ) and scanning nonlinear dielectric microscopy ( sndm ) were studied . to avoid the misreading of the same conductive tip with different state , a new method of polarization distribution mapping with nonconductive tip was proposed , and the result of experiment demonstrated that the polarization distribution of ferroelectric thin films could be characterized well by the new approach
