Temperature dependent growth and morphology of perylene thin films on gold substrates — •Phenwisa Niyamakom, Philip Schulz, Azadeh Farahzadi, Li Ding, Maryam Beigmohamadi, and Matthias Wuttig — Institute of Physics (IA), RWTH Aachen University, 52056 Aachen, Germany

In this study, the influence of substrate temperature on the growth and morphology of thin perylene films deposited on gold substrates us studied. The films have been deposited at different substrate temperatures and film thicknesses by vacuum thermal evaporation (VTE), have been investigated. Atomic force microscopy (AFM) has been performed to study film morphology as the surface roughness and evolution of perylene film growth. The structural properties and molecular vibrations of perylene thin films have been studied by X-ray diffractometry (XRD) and Fourier transform infrared spectroscopy (FTIR). Finally, a model for the perylene thin film growth is presented.
