摘要

The homogeneity of the lattice spacing of silicon single crystals was investigated by the self-referenced lattice comparator. Strain measurements were performed on single crystals from Avo28 ingot, which was used to determine the Avogadro constant. A swirl pattern was observed for the sample of 9.R1 cut from the Avo28 ingot.
