Abstract

In this paper, we will outline the architectures of photodetectors and light emitting diodes based on the van der Waals heterostructures. For the demonstrated photodetectors, we will show that they not only can exhibit the features of linear-dichroic, broadband and fast (> 200 MHz) photodetections at room temperature, but also can be useful for mid-infrared imaging applications. Regarding to the light emitters, we will show that the vdW-based light emitting diodes are applicable to the visible spectral region. In addition, the demonstrated vdW light emitting diodes can be further integrated with photonic crystal cavities, and the integration would significantly enhance the efficiency of light emission and lead to the high degree of linear polarized electroluminescence.
