研究发现,通过真空蒸镀制得的聚苯硫醚(PPS)薄膜具有电学双稳态的特性.由PPS薄膜制备的器件结构为:玻璃/ITO/PPS(300nm)/金.施加5s的80V电压脉冲可将PPS薄膜转变为低阻态,再施加5s的100V电压脉冲则可将其转回高阻态.此特性有可能应用于数据存储.作为存储器件,其临界电压为40V,其读取电压为5V.实验表明,外加电压下PPS薄膜电导状态的改变可能与C,S之间的电子转移有关. It was found that the polyphenylene sulfide (PPS) film prepared by vacuum evaporation has the characteristics of electrical bistability.The structure of the device prepared from the PPS film was glass / ITO / PPS (300nm) / gold. The voltage pulse transforms the PPS film into a low-impedance state, which can be turned back into a high-impedance state by applying a 100V voltage pulse for 5 s. This feature may be used for data storage. As a memory device, the threshold voltage is 40V, Take the voltage of 5V. Experiments show that under the applied voltage PPS thin film conductivity state changes may be related to C, S electron transfer between.
