▎ 摘  要

We employ ZnSe films and graphene to act as light-absorbing layer and channel, respectively. Lowflexibility yet high-absorbance ZnSe light-absorbing layer makes contribution to the absorbance and have no negative impact on the device flexibility, while high- flexibility graphene films determine the flexibility. As a result, the image sensors based on 4-inch flexible ZnSe/graphene hybrids with a high responsivity of 1.5 x 10(6) A/W could work stably under the large strain up to 0.2%. This is one order ofmagnitude larger than that of pure ZnSe films-based devices. More importantly, they make a stable performance under the strain of 0.2% after 10,000 bending cycles or a bending duration of 1000 h.
