近年来，微纳加工技术的不断突破促使电子器件的尺寸达到了纳米量级。随着电子元件的小型化，量子效应的制约愈发显著，致使摩尔定律受到挑战。因此迫切需要开发新型纳米电子器件，旨在不牺牲性能的前提下减小器件尺寸，从而达到器件低功耗、高效率、高集成度的目的。二维范德华材料展现出许多不同于相应体材料的新颖物理特性，使其在新型光磁电功能器件等领域展现出较大应用潜力。进一步将不同物性的二维材料堆叠起来制成范德华异质...
飞速发展的自旋电子学技术旨在研究高速、低功耗的电子元器件，与传统电子学利用电子的电荷相比，自旋电子学利用电子的自旋作为信息传输载体，在纯自旋流的情况下，传输通道没有耗散，即不会发热；同时，得益于自旋相干效应，信息具有很快的传输速度。当今自旋轨道矩（SOT）材料的研究主要集中在过渡金属及其合金以及拓扑绝缘体。过渡金属氧化物是一个很大的材料体系，有着丰富的物理性质，比如强的自旋轨道耦合效应（SOC）和...
