Abstract
This research is related to the growth and characterizations of the novel hybrid nanomaterial, tin doped zinc-phthalocyanine thin films (Sn-doped ZnPC), grown by thermal co-evaporation. The concentration of Sn in hybrid films was controlled by adjusting the deposition rate between Sn and ZnPc. The hybrid films were characterized by atomic force microscopy and UV-visible spectroscopy to reveal the physical and optical properties of hybrid films. Moreover, the electrical properties, e.g., carrier mobility and carrier concentration, of the indium tin oxide (ITO)/Sn-doped ZnPc/ aluminium (Al) devices were extracted from the current-voltage and capacitance-voltage characteristics. Furthermore, X-ray photoelectron spectroscopy and Raman spectroscopy was employed to explore the chemical interaction taking place in doped films. Sn doping into ZnPc changes the film's specific properties, e.g., morphology, crystalline packing, absorption spectra, and conductivity. Moreover, no chemical bond is formed between Sn and ZnPc, and Sn dopants are formed as metal clusters covered by derivative oxide (SnOx) embedded in the Sn-doped ZnPc film.
