Following our previous work on the united-atom simulation on octacosane (C28H58) (Dai et al., Phys. Chem. Chem. Phys., 2021, 23, 21262–21271), we developed a coarse grain scheme (CG10), which is able to reproduce the pivotal phase characteristics o

We used the united-atom scheme to build three types of crystalline structures for octacosane (C

We study the role of via size and aspect ratio in defect-free electroplating of through silicon vias in 3DICs. Using a level-set curvature enhanced adsorbate coverage model, we simulate the electroplating of vias of various sizes and aspect ratio by

We present multi-scale models providing guidelines for defect free growth of filling of through silicon vias (TSV) by electroplating. Using first-principles calculations, we understand the chemistry of the electroplating process. We use density funct

The nanocrystallization of mechanically milled amorphous alloys was examined both experimentally and theoretically. Mechanical milling induces the precipitation of nanocrystals in an initially amorphous Nd–Fe–B magnetic alloy. The effects of mill

Use of molecular dynamics (MD) as the “frontend” in a multi-scale simulation requires high accuracy and therefore demands significant computer resources, particularly for obtaining interfacial properties. In this work we investigate the computati

We have used a phase field model of a polycrystalline alloy, presented in [Acta Mater. 51 (2003) 4761], to study the effect of enhanced atomic mobility at the grain boundary (GB) on spinodal decomposition (SD) in two dimensional systems. For sufficie
