a, c Variation in the transfer characteristics of the photodetector based on 1-P/DPA crystal (a) and 1-M/DPA crystal (c) tested upon exposure to RCPL (red line) and LCPL (black line) illumination. b, d Real-time change in drain current ID in response to LCPL and RCPL illumination for the photodetector based on 1-P (b) and 1-M (d) started with the illumination of LCPL and changed during the test. ID was recorded at a constant drain and gate bias of VD = −60 V and VG = −10 V. The green shading and gray shading are tested with the illumination of LCPL and RCPL, respectively.
