Defects in CVD Diamond Films
-
摘要: 研究了利用直流電弧等離子體噴射(DC Arc Plasma Jet)的制備的大面積金剛石膜中的缺陷問題.研究表明:金剛石膜中的缺陷包括表面缺陷、晶內缺陷和晶界缺陷,以及由于內應力產生的金剛石膜宏觀和微觀裂紋.金剛石膜中的缺陷與制備工藝參數有著密切關系.Abstract: The defects in large area diamond films prepared by DC arc plasma jet CVD method are researched. The defects in diamond films are investigated, including the surface, bulk, boundry defects and the macro-cracks and micro-cracks caused by internal stresses. The results show that the growth parameters often led to defects in diamond films.
