Vacancy assisted formation of krypton bubbles in copper
Abstract
In the present work, vacancy enhanced krypton bubble formation in copper is studied with TEM. The vacancy concentration in excess of that produced by the energetic Kr atoms themselves has been introduced by implantation of Cu ions into Kr-preimplanted and subsequently annealed Cu specimens. TEM examinations reveal gradual increase of the fraction of Kr atoms gathered into bubbles, with increasing number of Cu 2+ irradiation-annealing treatments, which eventually reaches 100%. A good correlation between the number of radiation vacancies and the number of vacancies contained by bubbles is found.
