摘要：

In this work we use atomic force microscopy and X-ray diffraction to study morphology and growth kinetics of para-sexiphenyl layers deposited by hot wall epitaxy on crystalline KCl(001) substrates. It is shown that the growth on KCl(001) is characterized by co-existence of long needles ("laying" molecules) and terraces structured islands ("standing" molecules). The former are the initial growth stage of the films, generating a rectangular network in accordance with surface symmetry of the substrate. It is in contrast to mica substrates, where para-sexiphenyl forms only needles with one preferential direction. (C) 2004 Elsevier B. V. All rights reserved.
