摘要
The dissociation of CuCu-related centers in p-type silicon is studied as a function of temperature just after copper contamination with subsequent quench when a significant concentration of copper remains at interstitial site, and after a long storage time. The binding energy of Cu-pair related centers is determined to be 1.02+/-0.07 eV. Some conclusions on the mechanism of copper precipitation are made. It is suggested that the potential barrier for copper precipitation of 0.55 eV is due to the coulombic repulsion between the interstitial copper atoms and the positively charged copper precipitates.
