Abstract

Conductive-tip atomic force microscopy (C-AFM) is a powerful tool for investigating the electrical characteristics of phase-change materials commonly used for electronic and optical data storage. We demonstrate the usefulness of this technique by examining the electrical conductivity of crystalline marks recorded with a focused laser pulse on a thin Ge 2Sb 2Te 5 film. © 2012 WILEY-VCH Verlag GmbH & Co.
