MDS Investigation on the Melting and Solidification of Silver Nanoparticles
Paper in proceeding, 2018

Nano-silver pastes have been widely used in electronic packaging because of its outstanding characteristics in the electrical, thermal and mechanical aspects. The sintering process of silver nanoparticles has a great impact on the material features, performances and reliabilities. In the present paper, molecular dynamics (MD) simulations have been carried out, and the melting and solidification process of silver nanoparticles are studied. The phase transformation processes of nanoparticles were analyzed, and various temperature ranges has been considered. The relationship between the temperature and the system energy reflects the melting process, and the atom distributions at characteristic temperature points were observed. The structural development during the sintering of nanoparticles was studied, and there appears the coexistence of different structures in the crystallization.
