Exploiting the IR Transparency of Graphene for Fast Pyroelectric Infrared Det…

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 i…
