Nanocrystal formation in the quartz single crystal due to thermal vibrations of dislocations
V. I. Vettegren, R. I. Mamalimov Ioffe Institute, St. Petersburg
Abstract:
Structural changes in the layer $\sim$10 $\mu$m thick on the natural growth surface of the quartz single crystal with increasing temperature have been studied using infrared spectroscopy. It has been found that above 500 K the single crystal in this layer is split into nanocrystals with linear sizes from $\sim$8 to $\sim$28 nm. This effect has been explained by “unfreezing” transverse vibrations of growth dislocations.
