On Atomic Surface Roughness Evaluation

Abstract:

The atomic surface finish or roughness can be defined as the roughness limit of a surface. Its value has been demonstrated both in theory and in experiments to be non-zero [1, 2]. This parameter is very important in assessing the quality of high performance nanosurfaces, and so its understanding is very crucial. In this study, multi-pass nanometric atomistic simulations were carried out, with a diamond tool on a copper workpiece to create a nanosurface and the results provide the platform from which the atomic surface roughness was evaluated. The estimated surface roughness (Sa) was in the order of 0.3nm.
