Precise measurement of the refractive index of stable silicon isotopes Si, Si, Si single crystals with enrichments above 99.9 at.% and a silicon single crystal Si of natural isotopic composition is performed with the Fourier-transform interference refractometry method from 1.06 to more than 80 μm with 0.1 cm resolution and accuracy of 2 × 10 . . . 1 × 10. The oxygen and carbon concentrations in all crystals are within 5 × 10 cm and the content of metal impurities is 10 . . . 10 at.%. The…

Quantum Isotope Effect in Silicon at Low Temperatures

High-precision studies of Raman scattering in isotopically pure 28Si, 29Si, 30Si single crystals have been performed in the temperature range from 8 to 300 K. It has been found that a difference of
