“…As both crystal orientations (type S and A) form significantly different morphologies, XRD results can be nicely correlated with the sample morphology obtained by AFM 12,28 for 6T deposited on muscovite [ Fig. 3(a)] and phlogopite mica [ Fig.…”

“…While the first finding is often observed for epitaxially grown organic thin films, [30][31][32][33] the latter one is a strikingly uncommon finding. 28,34,35 In order to understand this surprising observation, an in-depth analysis concerning the relationship between crystals of type S and A has been performed. The relationship between the two domains contributing to the SAED pattern shown in Fig.…”

We present a systematic study on the epitaxial growth of α-sexithiophene (6T) on two different types of substrates, phlogopite and muscovite mica. The study is based on a structural and morphological analysis using specular x-ray diffraction, x-ray diffraction pole figure technique, transmission electron microscopy, atomic force microscopy, and optical microscopy. It is shown, that 6T molecules on mica substrates crystallize in two different configurations, characterized either by the (411) or (100) contact plane. Whereas the first orientation consists of needle-like structures, the latter one forms an island-like morphology, and both crystal orientations exhibit a well-defined relationship with respect to each other. We demonstrate that this finding can be explained by directed epitaxy of islands along the sidewalls of the needle-like structures.

“…The rocking curve can be fitted by a Lorentzian function which leads to the corrected mosaicity of the thin film of 1:5 . Compared to other organic films of rod like molecules the out of plane mosaicity (less than 0:2 for 6P on KCl [28,29]) is rather large but shows a clear preferred orientation. Specular scans of thinner films (using a wavelength of l ¼ 1:125Å) yield that the diffraction peak of 6T(0 2 0) is observed down to a film thickness of 16 Å .…”

“…The hot-wall method is a deposition technique under thermal equilibrium conditions and allows to grow highly ordered thin organic films. Therefore, the hot-wall method has been applied to grow well-ordered organic thin films such as parasexiphenyl [2,3], C 60 [4] and rubrene [5]. This growth method has also been applied for growth of Alq 3 films [6].…”
