  1. Based on sndm technique, a method of local capacitance - voltage characteristic characterization of ferroelectric thin films was proposed. the effect of traps at oxide - semiconductor interface on metal - oxide - semiconductor structure capacitance - voltage curve was discussed, and the influence of coercive field to the capacitance - voltage characteristics of ferroelectric thin films was also discussed. the dynamic switching of ferroelectric domain in ca doping ( pb, la ) tio3 thin film was studied by sndm from the view of electricity

    利用sndm ，從純電學的角度觀察了plct薄膜中的電疇動態反轉過程，由電疇橫向擴張的移動速度的降低，發現了晶界在電疇反轉過程中對疇壁移動的阻擋作用;根據sndm和pfm的在垂直方向上的不同信息敏感深度，得到plct薄膜中電疇反轉過程中電疇是楔形疇;用pfm觀察同一電疇在去掉外加反轉電場后電疇的極化弛豫現象，結果表明空間電荷是發生極化弛豫的主要原因。
  2. Investigation of domain and pyroelectric properties of lanthanum - doped lead titanate ferroelectric thin films

    摻鑭鈦酸鉛鐵電薄膜的電疇與熱釋電性能研究
  3. The work provides not only the foundation of studying domain structure in ferroelectric thin films but also the means of studying fatigue and polarization retention in ferroelctrics

    採用改裝的直流電源成功地對樣品進行了反轉，並利用pfm研究了鐵電疇的極化反轉。
  4. _ based on the domain switching behavior of ferroelectrics, a model of " successive switching " for ferroelectric domains is introduced. this may help to avoid some of the intrinsic limitations of the " complete switching " hypothesis, and be a more physical representation

    其工作包括： ? ?在分析鐵電材料電疇翻轉基本特徵的基礎上，引入電疇的「連續翻轉」模型，克服了「完全反轉」假設對鐵電特性描述的局限性，使電疇翻轉模型的物理意義更為明確。
  5. Analysis of domain reversal characteristics of plzt ferroelectric thin film

    鐵電薄膜反轉特性分析
  6. It was proposed that the reduction in pr ( n ) during the electric fatigue process was probably caused by the increase of a domain and anti - ferroelectric c * domain ( both leading to the increase in non - switching of c domain ) in combining with the experimental observation that the pr ( n ) values lowered with the rise of n. the equation which can be used to calculate the differences in non - switchable domain due to the increase of n was also given. variations of domain - switching with changes of n are discussed according to the in - situ xrd measurements

    根據原位xrd實驗觀測結果，給出了c a疇的90疇變的近似估算公式，並結合宏觀剩餘極化強度隨n增加而降低的實驗觀測，提出了疲勞過程中材料的剩餘極化強度p _ r （ n ）降低是由於a疇的增加和反鐵電c ~ *疇增加導致不可翻轉c疇增加共同造成的假設，並給出了不可翻轉疇隨n增加而變化的估算公式。
