Effect of grain size on thin film stress and morphology using kinetic ...

For smaller grain sizes, the stress is more tensile at high growth rates and more compressive at low growth rates than for larger grain sizes.

The effect of grain size on river delta process and morphology

As grain size increases delta morphology transitions from elongate to semi-circular because the average topset gradient increases. For a given set of flow ...
