To validate the accuracy of the trained DP model, the calculated radial distribution function (RDF) from AIMD, DP and Tersoff, are plotted in Figure 9. The DP model-generated RDF is very close to that of AIMD, which indicates that the crystalline structure of graphene can be well presented by the DP model. … See more A container is a portable unit of software that combines the application, and all its dependencies, into a single package that is agnostic to the … See more The first step in the simulation is data generation.
