利用单分子磁体Mn(dmit)2和磷烯电极构建了多效分子器件。第一原理量子输运计算表明,该器件表现出优异的自旋过滤、自旋转换和负微分电阻效应,这可以通过前沿分子轨道、预计态密度和透射光谱的演化来解释。这些优异的自旋输运性能优于由金或石墨烯电极构建的器件的性能,这表明带有磷烯电极的一维器件是基于磷烯的多功能自旋电子器件未来应用的有希望的候选者。
Multiple-effect molecular devices have been constructed by single molecule magnet Mn(dmit)2 and phosphorene.electrodes. First-principle quantum transport calculations show that the devices present excellent spin-filtering,.spin-switching and negative differential resistance effects, which can be explained by the frontier molecular.orbitals, the projected density of states and evolution of the transmission spectra. These excellent spin transport.properties are better than the performance of the devices constructed by Au or graphene electrodes, which.suggest that the one-dimensional devices with phosphorene electrodes are promising candidates for future applications.of phosphorene-based multi-functional spintronics devices.
