论文摘要
由于其石墨烯样的二维结构，提出了分层的过渡金属二分裂基化元素作为范德华（VDW）异质结构的构件。为此，磁性半导体可以代表各种旋转器和拓扑设备的宝贵组件。在这里，我们将不同的局部磁探针光谱与角度分辨光发射和密度功能理论计算相结合，以表明2H-MOTE2即将成为磁性。我们的结果提出了明确的证据，表明磁性可以通过类似氢的杂质“打开”。我们还表明，这种磁性状态可以生存到自由表面区域，证明了材料作为薄膜异质结构的磁成分的潜在适用性。
Layered transition-metal dichalcogenides are proposed as building blocks for van der Waals (vdW) heterostructures due to their graphene-like two dimensional structure. For this purpose, a magnetic semiconductor could represent an invaluable component for various spintronics and topotronics devices. Here, we combine different local magnetic probe spectroscopies with angle-resolved photoemission and density-functional theory calculations to show that 2H-MoTe2 is on the verge of becoming magnetic. Our results present clear evidence that the magnetism can be "switched on" by a hydrogen-like impurity. We also show that this magnetic state survives up to the free surface region, demonstrating the material's potential applicability as a magnetic component for thin-film heterostructures.
