Pentacene has long been studied as a model molecule for organic semiconductor thin film growth research, but studies on the initial formation process of parallel-oriented thin films are limited. In this study, pentacene submonolayers were deposited by varying the deposition time while maintaining the substrate temperature below -20°C and keeping the deposition rate constant. The change in island morphology with increasing coverage was observed using an atomic force microscope (AFM). By analyzing the nucleation density, the relationship between nucleation density and island growth in low-temperature growth was investigated.
