Abstract

This study presents the results of research on the roughness height parameters and lateral forces on the faces of cubes and octahedra of diamond single crystals and constructs maps of their distribution. The research was conducted using atomic force microscopy (AFM) and lateral force microscopy (LFM) using samples of type Ib and IIa diamond single crystals, grown using the high temperature and high pressure (HTHP) method. It was found that for type Ib diamond single crystals, the surface roughness (Ra parameter) of the cube faces is 3.3 times smaller, and that of the octahedron faces is 1.5 times smaller than for type IIa diamond single crystals. Additionally, for type Ib diamond single crystals, the lateral forces on the cube faces are, on average, 3.5 times smaller, while those on the octahedron faces are, on average, 9.5 times larger than for type IIa diamond single crystals. The results suggest that the level of lateral forces on the faces of diamond single crystals is determined by the roughness of their surfaces.

Ib型和IIa型金刚石单晶表面粗糙度和侧向力

本文介绍了金刚石单晶立方体和八面体表面的粗糙度高度参数和侧向力的研究结果，并构建了它们的分布图。采用原子力显微镜（AFM）和侧向力显微镜（LFM）对高温高压（HTHP）法生长的Ib型和IIa型金刚石单晶样品进行了研究。结果表明，Ib型金刚石单晶的立方体面表面粗糙度（Ra参数）比IIa型金刚石单晶小3.3倍，八面体面表面粗糙度（Ra参数）小1.5倍。此外，对于Ib型金刚石单晶，立方体面上的侧向力平均比IIa型金刚石单晶小3.5倍，而八面体面上的侧向力平均比IIa型金刚石单晶大9.5倍。结果表明，金刚石单晶表面的侧向力水平是由其表面粗糙度决定的。

期刊介绍： Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
