摘要：

A HfO2 thin film is incorporated into a resistive random access memory (RRAM) device based on conducting atomic force microscopy (CAFM). The RRAM element consists of an Au nanodot connected to a CAFM tip as an anode, a HfO2 channel, and a Pt electrode as a cathode. A nearly uniform Au nanodot array with a mean Au dot diameter of 25 nm is formed using a DBC nano-template and metallization techniques. The nanoscale HfO2 RRAM element exhibits unipolar resistive switching behavior similar to that of a typical RRAM bit. (C) 2011 The Electrochemical Society.
