Exploiting the IR Transparency of Graphene for Fast Pyroelectric Infrared Detection

---

In this study, we have exploited graphene’s unique combination of IR transparency and electrical conductivity to fabricate the fi rst pyroelectric IR sensor with graphene electrodes. We fi nd that the IR transparency of graphene enables an order of magnitude improvement in operating frequency, paving the way for faster thermal imaging than has been possible with pyroelectrics.Moreover, this is achieved without any degradation in sensitivity, as compared to pyroelectric sensors using the same polyvinylidene fl uoride (PVDF) active layer. Lastly, we demonstrate
that our device structure is compatible with pixelation,and fabricate an imaging system capable of capturing several
thermal images from a simulated scene. Our work thus highlights a new route for the utilization of graphene for infrared sensing, with the use of organic pyroelectrics opening the door for novel curved and fl exible thermal imaging applications.
