Abstract
Crystalline organic complex thin films have been performed by vacuum evaporation method on HOPG substrates.Using Scanning Tunneling Microscope storage,array has been made on the film by applying voltage pulses between the tip and the substrate.The recording marks are 1.3nm in diameter.Voltage-current characterization shows that the recorded region has a conductor behavior while the unrecorded regions shows an insulator behavior.It is confirmed from experiments that the distance between two recording marks can be as short as 2nm,which corresponds to the storage density of 2.5×1013bit/cm2.The mechanism about the recording is briefly discussed.
