导电率

The result showed that the carrier concentration of IMO was less than one third of that of ITO.So,the absorptance of visible light in IMO is lower than in ITO,there might br more space to improve the conductivity of IMO.

因此，IMO薄膜对可见光的吸收小，有很大的发展空间可以通过提高载流子浓度而进一步提高电导率，对近红外线也有较高的透射率，有利于拓展透明导电薄膜的应用领域。

Finally, a two-mask process was attempted to extend the same concept of the chip process. Here the mask of the contact aperture was replaced by the mask of the LED pad. After etching the SiO2 and ITO in the aperture region, a lateral etch of SiO2 was made to increase the ITO contact area. Although the forward voltage of the GaN LED shows a normal value, the process yield is still low and requires further study.

二道光罩制程延伸了三道光制程的理念，只是因为透明导电层的圆孔图形，是用电极的光罩去开的，所以蚀刻完二氧化矽膜及氧化铟锡膜后，必须再做二氧化矽膜的回蚀刻，让二氧化矽再内缩进去，以增加氧化铟锡和电极的接触面积，不会造成发光二极体的顺向电压提高，但因制程良率太低，所以还须要继续研究改善。

But if addition of static field was overhigh,RhB would directly take place electric oxidation, ITO/TiO_2/CdS composite films justacted as a conductive electrode with very large resistance, so the degradation rate ofITO/TiO_2/CdS composite films to RhB reduced instead.

如果外加电位过高，RhB就会直接发生电氧化，ITO／TiO_2／CdS复合薄膜只是作为一个电阻很大的电极来导电，所以本应该作为催化主体的ITO／TiO_2／CdS复合薄膜对RhB的降解率反而降低。

Due to big carrier concentration and optical band gap, transparent conductive oxide thin films exhibit outstanding optical and electrical properties, such as low resistively and high transmittance in the visible range etc.

透明导电氧化物薄膜材料具有大的载流子浓度和光学禁带宽度因而表现出优良的光电特性，如：低的电阻率和高的可见光透过率等。目前，此类材料体系包括In_2O_3、SnO_2、ZnO及其掺杂体系In_2O_3：Sn、SnO_2：Sb、SnO_2：F、ZnO：Al等。

According to the experimental results, both the conducting area and material of current collector slices have great influence on the performance of micro PEMFC, especially the former one. The increment of cell's performance is finite by increasing the gas reheats temperature. The performance is better for open ratio 75% compared with 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current density and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells' performances would be reduced.

由实验结果可知，集电片的导电面积与材料对於电池性能有显著的影响，尤其是前者；对於增加反应气体的再热温度，微型燃料电池增加的性能有限；双极板开孔率75%相较於开孔率为50%与67%有最佳的性能曲线；增加阴极气体空气的流量，可以改善高电流情况下的浓度极化现象，所以若我们能增加气体扩散层的扩散能力，则可以减少两者的性能差距。
