摘要:

二维范德华材料的垂直整合,预计会导致新的电子和光学性能没有发现在组成层。在此,我们将石墨烯与单层过渡金属二卤代化合物MoS 2,MoSe 2和WSe 2相结合,直接合成了两种独特的原子级薄的多结异质结构。MoS 2-WSe 2-Graphene和WSe 2-MoSe 2-Graphene异质结构的实现导致了原子级薄叠层中的共振隧穿,并具有光谱窄的室温负微分电阻特性。

英文摘要:

Vertical integration of two-dimensional van der Waals materials is predicted to lead to novel electronic and optical properties not found in the constituent layers. Here, we present the direct synthesis of two unique, atomically thin, multi-junction heterostructures by combining graphene with the monolayer transition-metal dichalocogenides: MoS2, MoSe2, and WSe2.The realization of MoS2-WSe2-Graphene and WSe2-MoSe2-Graphene heterostructures leads toresonant tunneling in an atomically thin stack with spectrally narrow room temperature negative differential resistance characteristics.
