Based On The Interface Study Of Self-assembled Film Electrical Storage Device

Part1Memory devices based on solid-liquid interface reactionOrganic electrical bistable device, which exhibits two different states of conductivities at the same applied reading voltage, namely, the effect of electronic bistability, is ideal for switch and memory used in digital circuits. And the so lid-liquid interface reaction is a brand new method used to create uniform films. Devices made of organic materials, based on solid-liquid interface reaction, which are believed to replace inor--ganic ones in the future due to the advantages of low cost, simplicity uniform, large area, and flexibility, have attracted considerable attentions and showed new develop direction of information industry.In this paper, we studied the organic material DMcT. We fabricated two types of thin films through solid-liquid interface reaction, which can be employed as the functional layer in write-once read-many-time devices (WORM). And we also studied the composition of the functional layers. Furthermore, we did some parameter optimization trials to improve the performance of the devices. Besides, combined with the I-V fitting, a detailed explanation was raised on the switching mechanism of memory devices. The specific works and results are as follows:1. We created a mono layer DMcT film through self-assembly. And we studied the performances about the device Al/DMcT/Cu based on the mono layer of DMcT film. As for the research, the resistive switching was attributed to the filament formation-rupture mechanism. Besides, we extended this system to other materials to get high-performance devices.2. We created Cu-DMcT metal coordination polymer film through solid-liquid interface reaction, with all kinds of characterizations analyzed the composition of the film and finally fabricated the memory device of Cu/Cu-DMcT/Al. The performance of the device was improved by optimizing the combination of each parameter.Part2Research on rectifier based on dynamic molecularFollowing previous researches of our lab, we studied the achievement of molecular rectification and further verified the high rectification ratio of the "’dynamic" model molecular rectifier in quantity.
