其次，我国国有企业的产权结构有其特殊性：所有权结构单一化，公有成分比总过大。 - When bath temperature t = 40oc , the deposited films have good surface and structure , the composition ratio sn / s is 1 , and its direct band - gap eg is 1 . 31ev
当温度为40oc时,所制备的薄膜具有较好的表面形貌,其成分比sn / s为1 ,薄膜的结晶性较好,且其直接禁带宽度为1 . 31ev 。 - In this paper ， first , the author drew some important conclusions by analyzing several technical factors and experimental conditions which would have great influence on the quality of diamond thin films during mpcvd process ， including gas proportion ， the power of microwave ， the plasma ' s location , the nucleation technique , etc . . finally ， the author has successfully deposited nanocrystalline diamond thin films with 300nm crystal particles on the slick surface of silicon by using ch4 / h2 gases in the mpcvd system ， and the nanocrystalline diamond thin films was proved to have good field emission performance . all these researches will make the foundation for the field emission cathode of diamond films
本论文中，作者分析了mpcvd方法中气源成分比、微波功率、等离子体球的位置、成核技术等各种工艺条件对金刚石薄膜质量的影响，并总结得到了一些有意义的结论；同时，在自行研制的mpcvd沉积系统上，于4 - 7kpa 、 1000左右的热力学条件下，采用ch4 / h2气源气氛在光滑的硅衬底上制备出了晶粒尺寸在300纳米以下的纳米晶金刚石薄膜，测试得到了较好的薄膜场致电子发射性能，为金刚石薄膜场致发射冷阴极的研究工作打下了实验基础。
