Abstract
⺠TaSin clusters on graphene surface keep its free ground-state structures. ⺠Graphene is helpful to a linear TaSi2 and a planar TaSi3 form their ground-state structures. ⺠The configurations of TaSin cluster on graphene are dominated by the interaction between Ta and graphene. ⺠For TaSin/graphene (n = 1and 2) system, charge transfers mainly from cluster to graphene surface, then from graphene to cluster as n â§Â 3. ⺠Chemisorption is dominant for TaSi and TaSi2 on graphene surface, while physisorption for TaSin (n â§Â 3) clusters.
