We have developed the theory of boundary shielding approximation of electric polarization, from which the values of spontaneous polarization of some typical ferroelectric materials can be derived. the shielded charges in ferroelectricity are in the state of surface bound polaron - dipole whose creation and annihilation must span a potential barrier. by introducing statistical method, four types of typical electric hysteresis loops of some common crystals and ceramics have been given, which are well consistent with the experimental results
利用電極化的邊界屏蔽近似，可計算出一些典型鐵電單晶的自發極化強度.鐵電屏蔽電荷處于表面束縛極化子偶狀態，其產生和湮沒要跨越位壘.由統計方法給出的一些常見晶體和陶瓷的四種典型電滯回線形狀，和實驗觀察到的結果一致 -

Main content of the thesis are also given in the introduction. the thesis presented three different of the residual stress based on x - ray diffraction - - two - exposure method, sin2, high - resolution reciprocal space mapping, which are applied to investigate the residual stress state of pt / ti bottom electrode stack, polycrystalline pzt ferroelectric thin films and epitaxial laalo3 / batio3 ferroelectric
基於此，提出了本文的選題依據，即研究鐵電薄膜中的殘余應力是基於「鐵電薄膜的重要應用背景和殘余應力對鐵電薄膜性能的可能影響以及目前鐵電薄膜中殘余應力研究的不足」 。 -
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
本工作主要分為以下幾個部分:從研究鐵電薄膜的壓電響應力顯微鏡（ pfm ）和掃描非線性介電顯微鏡（ sndm ）成像的影響因素入手，討論了針尖對成像質量的影響;為降低實驗成本、減小導電探針針尖狀態變化對鐵電薄膜微區電性能測試的負面影響，提出了以非導電探針檢測微區極性分佈的方法，並在現有spa - 300hv型spm的實驗平臺上以pfm模式成功實現了新方法對鐵電薄膜極性分佈的表徵。
