Molecular dynamics simulation investigation on the plastic flow behaviour of silicon during nanometric cutting

Molecular dynamics simulation (MDS) was carried out using two types of interatomic potential function (a modified version of the Tersoff potential and an analytical bond order potential (ABOP)) to acquire an in-depth understanding of the material flow behaviour of single crystal silicon during nanometric cutting on three principal crystallographic planes and at different cutting temperatures. T...

Molecular Dynamics Modeling and Simulation of Diamond Cutting of Cerium

The coupling between structural phase transformations and dislocations induces challenges in understanding the deformation behavior of metallic cerium at the nanoscale. In the present work, we elucidate the underlying mechanism of cerium under ultra-precision diamond cutting by means of molecular dynamics modeling and simulations. The molecular dynamics model of diamond cutting of cerium is est...

Wear-resistant diamond nanoprobe tips with integrated silicon heater for tip-based nanomanufacturing.

We report exceptional nanoscale wear and fouling resistance of ultrananocrystalline diamond (UNCD) tips integrated with doped silicon atomic force microscope (AFM) cantilevers. The resistively heated probe can reach temperatures above 600 degrees C. The batch fabrication process produces UNCD tips with radii as small as 15 nm, with average radius 50 nm across the entire wafer. Wear tests were p...
