Abstract

The Ag-TCNQ films with smooth surface and uniform tiny grains in nanometer scale were prepared by an improved vacuum evaporation method in which the deposition temperature of TCNQ films was increased from room temperature to 100degC. It is an ideal medium for ultrahigh density data storage with SPM-based techniques. Storage dots were recorded by applying voltage pulses between the tip of a scanning tunneling microscopy (STM) and the substrate under ambient condition. A recording pattern with six storage dots was obtained. The average diameter of recording dots was ~20nm, which corresponds to a data storage density of 0.5 Tbit/cm²
