| Popis: | A stretchable photodetector with enhanced, strain-tunable photoresponsivity is developed based on crumpled graphene by engineering 2D graphene into 3D structures. This crumpled graphene photodetector demonstrates ≈400% enhanced photoresponsivity led by an order-of-magnitude enhanced extinction of graphene and 100% modulation in photoresponsivity with 200% applied strain. Finally, strain-tunable, wavelength-selective photodetection is shown by integrated colloidal photonic crystals-crumpled graphene photodetector devices. |
