The Effect of Boron Additives on the Oxidation Rate of Synthetic Diamond Monocrystals
-
摘要: 本文用KNO3溶液氧化法对人造金刚石大单晶切片进行氧化实验,用两光束干涉计测量了单晶(含硼和不含硼)(110)截平面上各晶面成长区沿(110)面法线方向的相对氧化深度,计算了其相对氧化速度,并定性的与硼元素在这些区域的浓度做了对应。Abstract: By means of molten KNO3 oxidation experiments were conducted on the discs cut from a large synthetic diamond monocrystal. The relative depth of oxidation formed at sector boundaries on oxidized (110) cross-section of the diamond monocrystals (boron-doped and non-boron-doped) were measured with a two-beam interference microscope. The relative oxidation rates between growth sectors were calculated, and were connected with the amount of boron additive in these sectors.
