Surface morphological, structural, electrical and optical properties of annealed vanadyl tetra tert-butyl 2, 3 naphthalocyanine thin films

Vanadyl Tetra Tert-Butyl 2, 3 Naphthalocyanine (VTTBNc) thin films have been grown at room temperature by physical vapor deposition technique. The article describes the role of air and vacuum annealing on VTTBNc thin film surface morphology, structure, electrical conductivity and optical absorbance on the basis of respective measurements like atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray Diffractogram (XRD), DC electrical conductivity with integrated electrodes and UV–visible absorption spectra.

► VTTBNc thin films and VTTBNc/Silver(Ag) layers are grown by PVD technique.
► Post deposition air and vacuum annealing is done on films for conducting annealing studies.
► Annealing effects on various physical properties are carried out.
► Evidence of agglomerated structures are observed with good optoelectronic applications.
