However, as the hybrid systems seem to be sensitive regarding the process parameters, especially considering pulsing and purging times, there are systems with r values which are considerably higher than 1, e.g., TMA+heptanedioic

The crystal size (length and thickness) decreased with an increase of the chain length of the alkanes that formed these surfaces, whereas the density of the wax coverage, as well as the surface roughness, showed an opposite relationship.

We note that very recently it was shown that alkanes
