TLDR
In this article, the conditions necessary for order formation are analyzed for hexabenzocoronene (HBC) and naphthalene-tetracarboxylic-dianhydride (NTCDA) on graphite, MoS 2 and GeS.Abstract:
Epitaxially ordered thin films of large planar organic molecules can be obtained on layered inorganic semiconductors by organic molecular beam deposition in UHV. Analysis by low energy electron diffraction (LEED) and thermal desorption spectroscopy (TDS) yields structural parameters and binding energies. The conditions necessary for order formation are analyzed. Epitaxial data are given for hexabenzocoronene (HBC) and naphthalene-tetracarboxylic-dianhydride (NTCDA) on graphite, MoS 2 and GeS.read more

Structure and growth morphology of an archetypal system for organic epitaxy: PTCDA on Ag(111)
Bärbel Krause,A.C. Dürr,K. A. Ritley,Frank Schreiber,Helmut Dosch,Helmut Dosch,Detlef-M. Smilgies +6 more
TL;DR: In this paper, a growth temperature-dependent morphology transition from smooth films to well-separated islands has been observed which can be related to changes of the crystal structure, similar to the Nishiyama-Wassermann and Kurdjumov-Sachs relations.

Optical differential reflectance spectroscopy of ultrathin epitaxial organic films
Roman Forker,Torsten Fritz +1 more
TL;DR: This Perspective will give an overview on optical reflectance spectroscopy of highly ordered organic thin films in the thickness range from submonolayers to several monolayers, as a tool to study the absorption behavior of such films and emphasize the relations between the physical layer structure and the resulting optical properties.
