摘要

We use Kinetic Monte Carlo (KMC) method to investigate the evolution of Helium-Vacancy clusters under different conditions with emphasizing the influence of system temperature. Our simulation results indicate that when initial helium concentration increases, the size and amount of the Helium-Vacancy cluster will increase dramatically. The Helium-Vacancy cluster will become larger accompanied with a decrease in its amount as the temperature increases. The results also indicate that irradiating He-contained sample produces less helium bubbles compared with other conditions, adding helium during irradiating the sample or adding helium atoms after the sample have been irradiated.
