The lattice parameter of highly pure silicon single crystals

From crystal to crystal comparison, thed220 lattice spacing in PERFX and WASO silicon crystals used in the only two existing absolute measurements have been found to be equal within ±2×10−7d220. This demonstrates that generic variabilities of the two crystals account only for a small part of the 1.8×10−6d220 difference in the two absolute measurements. In a new series of 336 single measurements, ourd220 value reported recently has been confirmed within ±2×10−8d220. From these results we derive the following lattice parameter for highly pure silicon single crystals:a0=(543 102.018±0.034) fm (at 22.5°C, in vacuum).
