Argon Cluster-Ion Sputter Yield: Molecular Dynamics Simulations on Silicon and an Equation for Estimating Total Sputter Yield

Peter J Cumpson, Mieszko Jaskiewicz, WooKyun Kim

Argon Gas Cluster-Ion Beam sources have become widely-used on x-ray photoelectron spectroscopy (XPS) and secondary ion mass spectrometry (SIMS) instruments in recent years, but the…

The Role of Intermediate States in Low-Velocity Friction between Amorphous Surfaces

Woo Kyun Kim, Michael L. Falk

Simulated sliding between an oxidized silicon tip and surface over six decades of velocity using accelerated molecular dynamics reproduces the experimentally observed velocity depe…

Reformulating hyperdynamics without a transition state theory dividing surface

Woo Kyun Kim, Michael L. Falk

Reformulating hyperdynamics without using a transition state theory (TST) dividing surface makes it possible to accelerate conventional molecular dynamics (MD) simulation using a b…

Accelerated molecular dynamics simulation of low-velocity frictional sliding

Woo Kyun Kim, Michael L. Falk

Accelerated molecular dynamics (MD) simulations are implemented to model the sliding process of AFM experiments at speeds close to those found in experiment. In this study the hype…

Atomic-scale simulations on the sliding of incommensurate surfaces: The breakdown of superlubricity

Woo Kyun Kim, Michael L. Falk

Molecular dynamics simulations of frictional sliding in an Atomic Force Microscope (AFM) show a clear dependence of superlubricity between incommensurate surfaces on tip compliance…
