Determination of the structure and composition of the surface of polished single-crystal silicon artefacts used in the Avogadro approach to re-define the kilogram
A new definition of the kilogram is being sought. One approach is to relate the kilogram to an atomic mass through the accurate measurement of the Avogadro constant, and it requires the fabrication of near-perfect spheres from Si single-crystal material by a mechanical polishing process. Knowledge o...
