Preparation of PANI nanodots array and the Coulomb staircase phenomena

Abstract

PANI nanodots array was fabricated in AAO template with potentiostatic method in a short time. The topographic image of PANI nanodots array was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The I-V characteristics of conducting PANI nanodots array was measured with conducting atomic force microscope (C-AFM) in atmosphere at room temperature. Coulomb staircase phenomena was observed in the I-V curves.
