Large-area (3x3 mm2) flexible photodetectors were realized, based on crystalline InP
semiconductor nanomembranes transferred to flexible polyethylene terephthalate substrates. Very
low dark current a few microamperes and high responsivity 0.12 A/W were demonstrated for
flexible InP p-i-n photodetectors. Bending characteristics were also investigated for this type of
flexible crystalline semiconductor photodetector, and it was found that, whereas the dark current was
independent of bending radii, the photocurrent degraded, depending on the bending radii. © 2010
