通过电泳沉积将MoS2薄片受控地整合到纳米孔上
Controlled integration of MoS2 flakes on nanopores by means of electrophoretic deposition
摘要：
我们提出了一种简单而强大的战略，通过控制沉积的二硫化钼通过电泳过程的等离子体纳米孔上的二维材料薄片的通用集成。该方法既可以应用于简单的金属平面纳米结构，也可以应用于复杂的3D金属结构，两者都包括纳米孔。沉积方法允许用单层或几层MoS 2装饰等离子体结构的大型有序阵列。我们表明，由纳米孔产生的等离子体场可以与2D层显着相互作用，从而代表了一个理想的系统混合2D材料/等离子体调查。2D材料在等离子体纳米结构上的受控和有序集成打开了一条通往例如增强的光发射、来自等离子体混合结构的强耦合、热电子产生和基于2D材料的传感器的途径。
英文摘要：
We propose an easy and robust strategy for the versatile integration of 2D material flakes on plasmonic nanoholes by means of controlled deposition of MoS2 via electrophoretic process. The method can be applied both to simple metallic flat nanostructures and to complex 3D metallic structures both comprising nanoholes. The deposition method allows the decoration of large ordered arrays of plasmonic structures with single or few layers of MoS2. We show that the plasmonic field generated by the nanohole can interact significantly with the 2D layer, thus representing an ideal system for hybrid 2D-Material/Plasmonic investigation. The controlled and ordered integration of 2D materials on plasmonic nanostructures opens a pathway towards, for instance, enhanced light emission; strong coupling from plasmonic hybrid structures; hot electron generation; and sensors based on 2D materials.
