With the use of finite method we have developed computer simulation software for vacuum microtriodes with wedge - shaped and cone - shaped cathode on the basis of stduying deeply the field emission theory of vacuum microelectronics. the software included field section, grid point numbering, and the calculation of electric currents, transconductance and cathode capacitance, moreover, it can simulate the properties of vacuum microeletronic with variant structures and sizes. the relationship was studied and simulated among electic properties and device structures, sizes and cathode materials etc. the optimized design of vacuum microtiode was proposed
本文在深入研究真空微電子器件場致發射理論的基礎上,根據圓錐形、楔形陰極真空微電子三極體的不同特點,分別建立了物理和數學模型,在考慮空間電荷密度影響的前提下,以有限元法為基礎採用迭代的方法計算出真空微電子三極體內的電勢分佈情況,繪制出了等勢線、電子軌跡線,並得到了器件電學性能隨幾何參數的變化情況。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。The distribution regularity of polarization charge on the surface of spherical medium and electric field
介質球面上極化電荷及空間電場分佈規律Due to different trap depths, physical reactions and chemical reactions, space charge in frp rod materials had different polarities and densities is influenced by temperature evidently, especially between 20 and 40 and between 100 and 120
由於陷阱深度的不同和物理、化學變化的作用,不同溫度下芯棒材料內空間電荷的積聚極性和積聚量不同,特別是在20和40之間以及100和120之間存在明顯變化。The polymer is widely used in fields of electric and electronic insulation, but local fields ( electric fields, mechanical stress ) distortion induced by space charges in polymers will greatly affect properties of polarization, conductance, short - term breakdown and long - term breakdown
聚合物在電氣、電子絕緣中應用極為廣泛,但其中的空間電荷誘導的局部場(電場、力場)畸變,將對極化、電導、短時及長時擊穿特性帶來巨大影響。分享友人
