摘要：

Thin films of the organic semiconductor rubrene were deposited on muscovite (0 0 1) substrates by hot wall epitaxy. The morphology of rubrene thin films in combination with their crystallographic properties was characterized by transmission electron microscopy. The initial growth proceeds in a partially wetting regime where amorphous droplets are formed. Through diffusive interactions the droplets merge together in partially crystalline open networks. At a more advanced growth stage, spheruilites are formed and a variety of crystalline morphologies appears. Platelet- and needle-like morphologies can be assigned to the orthorhombic phase of rubrene with the [301] and [110] zone axes, respectively. (C) 2009 Elsevier B.V. All rights reserved.
