Computational modeling of fabrication of nanoneedle based on multi-physics analysis

Abstract

A three-dimensional model for fabrication process of Ag₂Ga nanoneedle based on phase field model has been performed. With the development of model, the fabrication of Ag₂Ga nanoneedle which is induced by chemical reaction has been well presented. The model incorporates a number of components, such as silver and gallium, which plays a crucial role in the diffuse and chemical reaction process. A phase field model is employed to describe the fabrication process and then supply reliable information to control the morphological evolution of Ag₂Ga nanoneedle. The purpose of this work is providing a reliable mechanism of fabrication process of Ag₂Ga nanoneedle in room temperature, and control the structure of nanoneedle in different temporal perspectives.
