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
實驗結果表明：隨著工作氣壓的減小，薄膜的晶粒尺寸有所減小；通過提高氫氣稀釋度，利用原子氫在成膜過程中起的刻蝕作用，可以穩定結晶相併去除雜相；選擇適當的熱絲距離能保證反應氣體充分分解，又使襯底具有較高的過冷度，是形成納米薄膜的重要條件；採用分步碳化法可以提高形核密度，有利於獲得高質量的納米- sic薄膜；襯底施加負偏壓可以明顯提高襯底表面的基團的活性，因負偏壓產生的離子轟擊還能造成高的表面缺陷密度，形成更多的形核位置。Based on the strong and effective collection and storage capacity of the group, we have set up our own collection, storage and processing system, including the storage yard of 50, 000 square meters, the processing and finished product storehouse of 2000 spare meters, and the large - scaly compositive machine that integrates rough selector, pebble selector, specific gravity selector, leash shifting machine and the granule size, in addition the hand - choosing workshop that can hold 250 people, can guarantee to offer high - quality products of more than 120 tons to customer every day
