Effects of {100} Seed Crystal Surface with Different Shape on the HPHT Synthetic Large Single Crystal Diamonds

  • 摘要: 选用不同形状的{100}金刚石籽晶面,以NiMnCo合金为触媒,利用温度梯度法在压力为5.5 GPa、温度为1260~1300 ℃的条件下,合成Ib型金刚石大单晶。通过光学显微镜和电子显微镜对晶体的形貌进行表征。研究发现,将合成籽晶的{100}晶面切割成不同形状,只会令晶体的长宽比发生改变,晶体并不会因籽晶形状的改变而偏离{100}晶体的正常形貌。晶体的合成质量受到籽晶长宽比的影响:在籽晶长宽比较小的情况下,晶体的合成质量能够得到保证;但当籽晶长宽比过大时,合成晶体的下表面出现较多缺陷。关于籽晶形状对晶体生长情况影响的研究,揭示了籽晶形状与合成晶体形貌之间的关系,有利于更深入理解晶体的生长过程和外延生长机理,对于今后合成不同形貌的金刚石具有借鉴意义。同时此项研究有助于扩大籽晶的选取范围,降低籽晶的选择难度,提升工业级金刚石的利用率,为合成金刚石大单晶的籽晶选取提供了技术支持。
