Abstract
⺠We study the self-diffusion dynamics of Cu adatoms on Cu(1 0 0) surface. ⺠The hopping of an active adatom is dependent on its nearest atoms and next nearest atoms. ⺠Dimers can move and rotate as a result of multiple hopping events, more readily than to dissociate. ⺠A triangle trimer can rotate more readily as a whole than to move. ⺠Adatoms on Cu(1 0 0) surface are inclined to aggregate to form compact islands at temperatures above 300 K.
