对金刚石膜中黑色缺陷的研究
Study on black defects in diamond films
摘要
Abstract
In order to improve the transparence of diamond films and the stability of technical parameters,the black defects of diamond films prepared with DC Arc Plasma Jet CVD method were investigated•The black defects after observation,analysis,measurement and comparison using several kinds of optical microscopes were classified into punctiform,massive,texture and lamellar defects•The punctiform black defects were produced by masking and scattering of light caused by granular metal impurity,carbon mass,cavity and penetrating twins in diamond films•The massive and stripped defects were produced by reflection and scattering of light caused by changes of surface angle and orientation between the crystal columns•The texture defects were produced by the stress in the diamond films• The lamellar defects were produced by absorption of light caused by conductive elements at different horizons of diamond films•The lamellar defects were the main light-blocked defects of diamond films because the existence of lamellar defects severely influenced the improvement and stability of transparence,abrasion ratio,thermal conductivity and three-point bending fracture strength of diamond films•Some ways to solve the black defects had been put forward.关键词
