As was discussed in the previous chapter, solid-on-solid models are ones where no overhangs are allowed on the simulated surface. These models are the simplest to implement because the height profile is a single-valued function of position, and as a result, are the most common discrete models utilized in modeling thin film growth. More complicated models, including ballistic aggregation models, have been of interest as well, but illustrating the formulation and use of solid-on-solid models first gives insight into the advantages and drawbacks of both types of models.
