Highly Ordered T6 Organic Semiconductor Networks on MoS₂ Nanosheets for Optoelectronic Applications.

ABSTRACT: Van der Waals 2D crystals, with their dangling bond-free surfaces and extremely low roughness levels, are highly appealing substrates for the epitaxial growth of organic semiconductors. The growth has important consequences in the fabrication of organic electronic components such as organic light diodes. Here, using a MoS₂ nanosheet, an n-type semiconducting 2D material, as a substrate, we grow highly ordered crystalline needles made of sexithiophene (T6), a p-type organic semiconductor. Using atomic force microscopy topographic analysis, X-ray diffraction, and micro-Raman spectroscopy, we show that the T6 needles show both short- and long-range order thanks to an alignment between the T6 long axis and high symmetry directions in MoS₂. By statistical analysis we demon
