PENGARUH LAJU TEMPERATUR SOLIDIFIKASI TERHADAP KRISTALINITAS NANO SENG OKSIDA DENGAN METODE SIMULASI MOLEKULAR DINAMIK

INFLUENCE OF THE SOLIDIFICATION TEMPERATURE RATE ON CRYSTALINITY OF NANO ZINC OXIDE BY MOLECULAR DYNAMIC SIMULATION METHOD

Abstract

The presence of nano technology has an important role in utilizing a material, considering the use of nanotechnology in Indonesia has been applied in various fields, in the formation of nano zinc oxide (ZnO) there is a solidification process where this process is the final stage in ZnO nano formation. In the dynamic molecular simulation method, the nano ZnO solidification process will be observed with variations in the solidification temperature rates of 10¹⁰K/s, 10¹¹K/s, 10¹²K/s, using LAMMPS software (Large-scale atomic / molecular massively parallel simulators) and OVITO as Help software from the results of the simulation process and VESTA-JP Minerals. From the simulation results, it can be concluded that the greater the solid temperature rate value the lower the nano ZnO crystallinity will be (amorphous).
