Nano cluster manipulation success considering flexibility of system: Coarse grained molecular dynamics simulations

In this paper, the results of using a coarse grained molecular dynamics (cgmd) model tosimulate the process of manipulation of nano clusters with a flexible tip are reported, and the reasonsfor some failures are discussed. after comparison of these results with those from a macro model, somefailures of the nano manipulation process, due to damage, fracture, or crushing of tip, substrate, and nanocluster, are examined. at the end, after a parametric study of nano cluster deformations, the use of the tipcluster, p-sp diagram, for optimal selection of the tip material, is discussed.
