Measurements of the forward I-V characteristics of these diodes have shown that thermionic emission current is the dominant current conduction mechanism for these Schottky contacts.

对研制的器件特性进行了比较分析，I-V特性测量说明Pt／6H-SiC肖特基二极管有较好的整流特性，热电子发射是其主要的输运机理，理想因子为1.23，肖特基势垒高度为1.03eV，开启电压约为0.5V。

It shows that the thermionic emission current can be influenced by the temperature, the work function, the diameter of the surplus RE particleand the electric field. The "nanometer particles" theory modification concentrates mainly on two parts. First, the active layer was described.

对"纳米微粒子"发射模型进行两方面的完善：其一、描述了表面活性物质层是非连续的薄膜；其二、当稀土氧化物晶体中的氧缺位浓度超过临界值的时候，即开始有纳米稀土粒子的形成和生长。

The thermionic emission and tunneling current dominate the conduction process at higher Xc. However, if the film has low Xc, which means lager barrier width, the tunneling current can be neglected.

首次运用二维结构渗流模型计算了微晶硅薄膜结构对电导率的影响，从理论上解释了造成微晶硅薄膜输运各向异性的主要因素是薄膜中晶粒的柱状生长。

In this paper, nanopowders of rare earth oxides and tungsten were prepared and 0-3 type nano-composit rare earth tungsten thermionic emission materials were fabricated with novel technics. The raw material selection, preparation technic parameter, structure, physical and chemical characteristic, the rare earth distribution and the emission behavior were studied. The influence between the active layer and the thermionic emission performance, rare earth elements diffusion and distribution along depth were investigated in detail. The surplus RE formation and the electron transfer were discussed in theoretically. The thermionic emission current density of the single surplus RE on the active layer was educed. We adopted "liquid-liquid mixing, freeze-drying and two stage-reduction" working step firstly to produce the RE-W nanopowders including La-W powder, Ce-W powder and Y-W powder.
