| 8. | By increasing the h2 dilution ratio , it is found that atomic hydrogen can selectively etch amorphous phase and stabilize crystalline phase . from the study on the distance from substrate to catalyzer , choosing a proper distance can ensure the gas fully decomposed , while a relatively low substrate temperature can cause the nanocrystalline particles to lose mobility and keep their sizes . the pre - carbonization process can enhance the nucleation density and make the growth of high quality nanocrystalline p - sic films much easier 实验结果表明:随着工作气压的减小,薄膜的晶粒尺寸有所减小;通过提高氢气稀释度,利用原子氢在成膜过程中起的刻蚀作用,可以稳定结晶相并去除杂相;选择适当的热丝距离能保证反应气体充分分解,又使衬底具有较高的过冷度,是形成纳米薄膜的重要条件;采用分步碳化法可以提高形核密度,有利于获得高质量的纳米- sic薄膜;衬底施加负偏压可以明显提高衬底表面的基团的活性,因负偏压产生的离子轰击还能造成高的表面缺陷密度,形成更多的形核位置。 |
| 9. | Ammonia played a critical role in the vertical alignment of cnts , and the possible reason was that in 850 the atomic hydrogen decomposed from ammonia reacted with amorphous carbon to form volatile products to keep the metal surface clean , and mechanical leaning against neighboring tu bes established a morphology of vertical alignment 当基体为单晶硅、催化剂镍膜厚度为20nm 、氨气气氛、生长温度为850时,得到了定向生长的纳米碳管。其原因可能是850时氨气分解的氢原子和无定形炭生成了易挥发物质,从而保持催化剂的活性使纳米碳管依靠相邻碳管之间的斥力定向生长。 |
