摘要：

Growth of ultrathin pentacene films is investigated as a function of coverage by atomic force microscopy. Initially, pentacene grows as monolayer fractal islands and evolves into compact islands before coalescence. Stabilization factors, against diffasion-limited-aggregation in terms of interaction between islands and interlayer monomer transport, are proposed to explain the shape transition. Simulations based on a simple model of heterogeneous film growth are found to agree with experimental observations. The role of surface diffusion in island shape transition is revealed by a comparison between pentacene growth on the hydrogen terminated and oxidized Si substrates. (c) 2005 Elsevier B.V.
