  1. In the framework of the transverse ising model ( tim ), landau phase transition theory and the electrostatic field theory, we study the physical properties of the ferroelectric thin film, bilayer, sandwich structure, multilayer with a non - polarization slab and a two - dimension polar lattice model with polar defects. the main work and results are as follows : first, the long - range interaction in ferroelectric material is sometimes neglected in the previous studies. we introduce the long - range interaction in the framework of the tim and the landau theory

  2. We find that i ) with the increase of the long - range interaction, the interfacial coupling and the thickness of one period, the phase transition temperature of the ferroelectric superlartice increases

    我們發現，隨著長程相互作用和界面耦合作用的增強以及鐵電超晶格尺寸的增大，整個材料的相變溫度升高。
  3. Dielectric response in ferroelectric phase transition in barium titanate powder

    粉料鐵電相變的介電效應
  4. A density functional theory investigation of the electronic structure and ferroelectric phase transition of batio3 and pbtio

    鈦酸鉛及鈦酸鋇的電子結構和鐵電相變的密度泛函理論研究
  5. But at low temperatures it deviates from the curie - weiss behavior and saturates at even lower temperatures, which can be attributed to the effect of quantum fluctuation that stabilizes the paraelectric phase and suppresses the ferroelectric phase transition entirely

    量子順電體的介電常數在低溫時呈現類似於居里-外斯定律的行為，即顯示出將要發生鐵電相變的徵兆，但直至最低溫度都不發生鐵電相變。
  6. The la - modified thin films with 220nm thickness exhibited diffuse phase transition through the testing of temperature dependence of dielectric permittivity. the abnormal dielectric phenomenon was explained according to the observed relaxor behavior. the influence of post - annealing on the properties of the ferroelectric thin - film capacitors is another component of this thesis

    在薄膜的介電性質方面，通過對介電溫譜的測試，發現對于厚度薄至220nm的薄膜，摻鑭后同樣會導致馳豫型的鐵電相變，並依此解釋了介電常數的「反常」現象。
  7. Polymer networks have been produced in a variety of liquid crystal phases in cells without surface treatment. the liquid crystal / monomer mixtures are prepared using a ferroelectric liquid crystal and a diacrylate monomer. the polymerisation of the monomer is carried out by uv curing the mixture when it was kept in a specific phase which can be obtained by controlling the temperature of the ferroelectric liquid crystal. both the monomer and the polymer network will depress phase transition temperatures. the effects of the polymer network on the packing arrangement of the ferroelectric liquid crystal molecules are examined by means of optical microscopy. the molecular packing arrangement of the ferroelectric liquid crystal in a specific mesogenic phase is frozen on the formation of a polymer network in the ferroelectric liquid crystal in that phase. the existence of the diacrylate based polymer network can improve the electrooptical switching of the ferroelectric liquid crystal

    在灌裝于未經表面處理的樣品盒內處于不同狀態的液晶中制備聚合體網路.液晶/單體混合物由鐵電液晶和雙丙烯酸單體製成.單體的聚合通過維持該混合物處在一定的液晶態的條件下經紫外線固化來完成.不同的液晶態可通過控制鐵電液晶的溫度來獲得.雙丙烯酸單體或聚合體網路的存在會導致鐵電液晶載體的相變溫度降低.通過光學顯微鏡可觀察聚合體網路對鐵電液晶分子組合排列的影響.結果發現:在某一液晶態中鐵電液晶分子的組合排列可被在該液晶態中聚合而成的聚合體網路所穩定，雙丙烯酸基聚合體網路的存在可改良鐵電液晶的電光開關特性
