摘要: Solid phase epitaxial growth of ion beam-amorphized α-quartz has been studied by means Rutherford backscattering spectrometry in channeling geometry. single crystals were irradiated with Cs+ and Xe+ ions annealed air or vacuum at 500–900 °C. Complete regrowth observed the Cs-irradiated samples, after 875 °C annealing air. On other hand, provided only incomplete amorphous layer, while Xe-irradiated could not be regrown up to 900 °C. The behavior Cs recrystallization process is discussed terms SiO2-network topology.
