چکیده انگلیسی
Self-doped conducting polymer, polyanthranilic acid (PANA) was synthesized and used for the first time for fabrication of contacts with the configurations (Al, Ti, Sn metal)/PANA/indium tin oxide (ITO) coated glass and Al/PANA/Pt-nano-probe using mico- and nano-meter thick PANA layers, respectively. The chemically synthesized PANA dissolved in methanol was deposited over the substrate (ITO coated glass plate/Al-flat electrode) using spin coating technique. The current-voltage (I-V) characteristics and diode performance parameters of micro- and nano-meter sized devices were compared and contrasted by using micro- and nano-contact arrangements. The I-V characteristics of the above two configurations exhibited a rectifying contact with Al and Ti metals and an ohmic contact with Sn. The morphology of polyanthranilic acid film was studied using atomic force microscope and UV-vis spectroscopic technique was used to obtain the optical bandgap of the polymer.
