TWO-DIMENSIONAL ATOMISTIC SIMULATION OF METALLIC NANOPARTICLES PUSHING

Abstract

Nanomanipulation as a new emerging area enables precise manipulation, interaction and control at the nanoscale. Currently, the modeling schemes are based on continuum mechanics approaches. A main consideration in the nanomanipulation process is the fact that surface attraction forces are greater than gravitational forces at the nanoscale. In other words, surface area properties dominate volume properties. Especially at the nanoscale (i.e. the manipulation of fine nanoparticles with size of about 5 nm) the physical phenomena have not been completely understood. Along this line of reasoning, the aim of this paper is to conduct an atomistic investigation of physical interaction analysis of particle–substrate system for manipulation and positioning purposes. In the present paper, 2D molecular dynamics have been conducted to simulate metallic nanoparticle behavior during the pushing process. Dependency of the aforementioned behavior on size, matter, temperature, etc. is investigated.
