Abstract
A theoretical approach to the self-organization phenomena in irradiated crystals, which contain traps for vacancies and interstitials, is developed. In considered system two kinds of dissipative structure can arise.
Temporal structures develop owing to release of energy in the processes of radiation-defect recombination and their absorption by sinks. The energy release results in crystal heating followed by defect diffusion intensification. Temporal structures are oscillations of defects density and crystal temperature. Their frequency ranges from 10−5 to 10− s−1.
Spatial periodic structures (superlattice of defect density) arise because of interaction between defects at defect production rate larger than certain threshold value. The superlattice period ranges from 10 to 1000 Å for tipical crystal parameters and irradiation conditions.
