“…The perylene derivative family is one of the most extensively studied organic semiconductor molecules. − In the field of organic electronics, perylene-based molecules are considered good candidates for optoelectronic and photovoltaic device applications due to their ability to form well-ordered assemblies on many surfaces. ,− In the previous work of Kampen et al, the orientation of PTCDI molecules was found to be tilted by about 50° with respect to the GaAs surface. Hiroshiba and co-workers evaluated perylene molecules with long alkyl chains (PTCDI-C8) and observed a preferential flat-lying configuration when thermally deposited on a SiO 2 /Si surface using X-ray reflection (XRR) measurements.…”

The molecular orientation of organic semiconductors on a solid surface could be an indispensable factor to determine the electrical performance of organic-based devices. Despite its fundamental prominence, a clear description of the emergent two-dimensional layered material-organic interface is not fully understood yet. In this study, we reveal the molecular alignment and electronic structure of thermally deposited N,N'-dibutyl-3,4,9,10-perylene-dicarboximide (PTCDI-C4) molecules on natural molybdenum disulfide (MoS) using near-edge X-ray absorption fine structure spectroscopy (NEXAFS). The average tilt angle determination reveals that the anisotropy in the π* symmetry transition of the carbon K-edge (284-288 eV range) is present at the sub-monolayer regime. Supported by ultraviolet photoelectron spectroscopy (UPS), X-ray photoelectron spectroscopy (XPS), and resonant photoemission spectroscopy (RPES) measurements, we find that our spectroscopic measurements indicate a weak charge transfer established at the PTCDI-C4/MoS interface. Sterical hindrance due to the C4 alkyl chain caused tilting of the molecular plane at the initial thin film deposition. Our result shows a tunable interfacial alignment of organic molecules on transition metal dichalcogenide surfaces effectively enhancing the electronic properties of hybrid organic-inorganic heterostructure devices.

“…These organic semiconductor (OS) devices are efficient and require a relatively smaller amount of power compared to traditional devices, furthermore OLEDs have great properties such as fast response speed and very good colour performance. Much research has been carried out in the exploration of new materials which are used for OS devices to improve their performance [2,3]. Nevertheless, the semiconducting monomer Alq 3 (Al(C 9 H 6 NO) 3 ) with the band gap (i.e.…”

The electronic structures of Alq3/Si(111) and Alq3/LiBr/Si(111) interfaces are presented in this report. The studies were carried out in situ in ultrahigh vacuum by ultraviolet photoelectron spectroscopy. Alq3 and LiBr layers were vapour deposited onto a single crystal of n-type Si(111). The energy level diagrams were prepared for the structures. The formation of the LiBr interfacial layer results in a decrease of the energy barrier at the interface.
