2D TMDCs-Based NIR Photodetector on a Silicon Microring Cavity

Here, we report a photodetector (PD) based on heterogeneous integration of Few-layer MoTe
₂
integrated on MRR by using our developed 2D printer technique. The device is realized in a two-terminal in-plane electrode configuration without applying external gating, showing a responsivity of (~0.1 A/W).
