论文摘要
我们报告了基于聚(乙烯基氟化物)(PVDF)的有机屏障的有机多型隧道连接(OMFTJ)的制造:FE3O4纳米复合材料。通过将Fe3O4纳米颗粒添加到PVDF屏障中,我们发现与纯PVDF屏障相比,OMFTJ的铁电性能得到了很大改善。它可能导致在10K时在10K时的隧道电气抗性(TER)约为450%,在室温(RT)时为100%,远高于基于纯PVDF的设备的隧道电阻(RT)(RT时为70%,在10K时为70%,RT时为7%)。基于PVDF:FE3O4纳米复合材料的OMFTJ可以通过纳米颗粒的磁性与有机屏障的铁电性的磁性相互作用来打开智能多表情器件的新功能。
We report on the fabrication of organic multiferroic tunnel junction (OMFTJ) based on an organic barrier of Poly(vinylidene fluoride) (PVDF):Fe3O4 nanocomposite. By adding Fe3O4 nanoparticles into the PVDF barrier, we found that the ferroelectric properties of the OMFTJ are considerably improved compared to that with pure PVDF barrier. It can lead to a tunneling electroresistance (TER) of about 450% at 10K and 100% at room temperature (RT), which is much higher than that of the pure PVDF based device (70% at 10K and 7% at RT). OMFTJs based on the PVDF:Fe3O4 nanocomposite could open new functionalities in smart multiferroic devices via the interplay of the magnetism of nanoparticle with the ferroelectricity of the organic barrier.
