Abstract
Infrared photodetectors (IRPDs) are of importance devices with wide applications from face identification to space communication. With the investigation of thermoelectric materials, perovskite and three-dimensional (3D) graphene have been demonstrated and fabricated to thermoelectric PDs with response to terahertz bands separately. Herein, we develop thermoelectric PD based on 3D graphene and perovskite hybrid material with good IR performance. The responsivity at 1 V bias reaches to 0.1 A/W, under the illumination of 1064 nm laser with the power density of 3.1 mW, corresponding noise equivalent power (NEP) 1 nW∙Hz-1/2 , the rise time 10.8 ms and fall time 12.8 ms, respectively. These results demonstrate these hybrid IRPDs show good IR performance, and can provide a reference for other spectral range such as terahertz bands.
