Wearable Mos2 Photodetector based on Quasi-Dry Layer Transfer Process

Here we fabricated a flexible MoS2 photodetector onto a transparent, ultrathin cellulose acetate substrate using a quasi-dry layer transfer process. The device showed the broadband photoresponse from ultraviolet to visible region. The maximum responsivity and detectivity of the MoS2/CA photodetector were found to be 9.1 mA/W and 2.82 × 1011 Jones, respectively. Additionally, the performance of the device was investigated with bending or strain, and it was shown that photocurrent is consistent with bending.
