Sci Technol Adv Mater. 2008 Nov 25;9(4):045006. doi: 10.1088/1468-6996/9/4/045006. eCollection 2008 Dec.

Abstract

Atomic force microscopy (AFM) is a universal imaging technique, while impedance spectroscopy is a fundamental method of determining the electrical properties of materials. It is useful to combine those techniques to obtain the spatial distribution of an impedance vector. This paper proposes a new combining approach utilizing multifrequency scanning and simultaneous AFM scanning of an investigated surface.

Keywords: atomic force microscopy; dynamic electrochemical impedance spectroscopy; non-stationarity.
