With different combinations of 2D materials / ferromagnetic metal heterostructures, one could possibly generate large Rashba effective field by flowing charge current along the 2D/FM interface. Recently, it has also been reported that the large Rashba effect therein can further induce significant spin-orbit torques. In this project, we would like to explore spin transport properties in various 2D/FM heterostructures and to develop potential spin-orbitronics devices.二維材料異質介面自旋電子自旋軌道矩2D materialsheterostructurespintronicsspin-orbit torque「台大核心研究群」計畫【二維材料異質結構中之介面 Rashba 效應與其自旋軌道矩】
