Fig. 6: Time responses and variation in electrical properties under different SVA treatment conditions.

a, b Time responses via the photoelectric dual-control measurement (orange line filled with circles for Device #5, blue line with filled circles for Device #6, tr for rise time, tf for fall time). c Variation in ∆Iph (red line with filled circles) and Vo (blue line with filled circles) with increasing SVA temperature (light purple area represents the device without SVA, light blue area represents the devices with SVA (20 min)). d Variation in ∆Iph (red line with filled circles) and Vo (blue line with filled circles) with increasing SVA time (light purple area represents the device without SVA, light blue area represents the devices with SVA (100 °C)). The light intensity is 0.04 mW/cm2 @ 850 nm.
