Molecular Dynamics (MD) Simulation on the Collision of a Nano-Sized Particle onto Another Nano-Sized Particle Adhered on a Flat Substrate

Yi M-Y, Lee J.W., Pohang University of Science and Technology, KR

Efficient cleaning of nano-sized particles from substrates becomes more and more crucial in nano fabrication. One promising technique is to bombard the contaminant particles with nano-sized bullet particles, but details of the collision process between [...]

Evaluation of Manipulation Probes for Expanding the Range of Capillary Force

Obata K.J., Saito S., Takahashi K., Tokyo Institute of Technology, JP

It is difficult to manipulate a micro-sized object precisely with conventional tools, because the gravity effect becomes extremely small compared to the adhesional one. Therefore, in order to perform reliable micromanipulation, we need to use [...]

Criterion for Electrostatic Detachment of an Adhering Microparticle

Saito S., Himeno H., Takahashi K., Onzawa T., Tokyo Institute of Technology, JP

During micromanipulation, the influence of gravitational force becomes extremely small. The adhesional force is more significant for smaller objects. An adhered object can be detached by electrostatic interaction. In our earlier study, the electrostatic force [...]

Introduction of Micro-Manipulation by Adhesional Force and Dielectric Force

Takahashi K., An Y., Saito S., OnzawaTadao T., Tokyo Institute of Technology, JP

This paper reports the manipulation by both adhesional force and Coulomb force. Applicability of this method is discussed evaluating both of the forces theoretically and experimentally. Adhesional force can be used as attractive force in [...]

Large-scale Simulations of Adhesion in Dense Polymer Melts

Sides S.W., Grest G.S., Stevens M.J., Sandia National Laboratories, US

We study adhesion between a polymer melt and substrate due to tethered chains on the substrate surface. We have performed extensive molecular dynamics simulations to study the effect of tethered chain density (S), tethered chain [...]
