Abstract
We have investigated the evolution of the growth front of perylene, an organic semiconductor with high carrier mobility, on glass and Au substrates grown side-by-side by vapor deposition. The films were grown with gradually increasing thickness which allowed us to examine both the spatial and temporal correlation of the surface roughness using atomic force microscopy. Our results show that perylene growth on glass and Au substrates is non-stationary. However, the instability during the growth is shown to depend largely on the substrate. A roughness exponent of 0.82 is obtained for glass and 0.84 for Au. A growth exponent of 0.21 is obtained for glass and 0.74 for Au. The results indicate the strong influence of the substrate on the film morphology and point to possible ways to control and improve it.
