Grad Seminar: Low-dimensional Carbon Materials for Self-power Broadband Detectors
Abstract
Real-time, room-temperature operation and self-powered photothermoelectric (PTE) detection emeries are advanced and versatile solutions for various applications. These detectors offer the advantage of not requiring external power sources, making them portable and suitable for remote or low-power environments. Additionally, their ability to operate at room temperature eliminates the need for costly and complex cooling systems, making them more accessible and cost-effective for various industries and research fields. However, issues of massive fabrication, complicated manipulations, long-term stability, and flexibility are concerned with engaging new exploration on PTE detectors. Low-dimensional materials are emerging as leading ones due to their broadband detection from Terahertz (THz) to ultraviolet (UV), electrical conductivity with a small band gap, and strong polymer affinity for thermoelectrical conversion. This seminar aims to use low-dimensional for exploring new PTE detectors, guiding materials methodology, leading the investigation of polymer composites, and providing insights into various industrial, imaging, and health monitor applications.
