Grad Seminar: System Design of Mid-/Far- Infrared Photothermoelectric Detectors

Abstract

Self-powered, flexible, and uncooled mid-wavelength infrared (MWIR) detectors based on photothermoelectric (PTE) mechanism are promising in the next-generation wearable Internet of Things (IoT). The photovoltage of PTE detectors is controlled by the Seebeck coefficient and temperature difference under local or global illumination. Previous PTE detectors show a less outstanding performance enhancement, and rare papers report their potential applications. Herein, we propose the PTE detectors utilizing the low-dimensional materials and polymer composite applied for non-contact wearable applications and non-destructive tracking (NDT). We also propose some design of flexible and Si-based PTE detectors, whose optoelectrical performance and advantages/disadvantages will be also presented. Our direction open new paths toward low-cost and high-performance wearable flexible applications as well as other biomedical or IoT-related aspects.
