极化场调控的热释电光电探测器:从均匀极化到梯度极化
Polarization-field-tuned Pyro-phototronic Detectors:From Uniform Polarization to Gradient Polarization
摘要
Abstract
Miniaturized,low-power,and high-performance photoelectric sensor is a key research topic in integrated optoelectronic chips and intelligent sensors.Particularly,pyro-phototronic detectors have emerged as a vital research direction in optoelectronic sensing due to their self-powered capability,fast response,high responsivity,and broad bandwidth.Here,the fundamental principles of pyro-phototronic effect are elucidated,followed by an overview of per-formance optimization strategies and specialized applications of this effect in various junctions-based photodetectors.Subsequently,enhancement of non-uniform polarization field on pyro-phototronic effects in PN junctions is demonstrat-ed through enhancement mechanism and constructing methodologies for gradient polarization fields.Based on the engi-neered gradient polarization,we achieved the PN-junction pyro-phototronic detectors with superior performances in re-sponsivity and spectral bandwidth.Finally,we offer insight into the future development of pyro-phototronic detectors in design principles,device architectures,and specific applications.The studies on polarization-field-tuned photodetec-tors offer flexible design paradigms for advancing pyro-phototronic sensing,which might significantly accelerate the practical applications of pyro-phototronic detectors in smart sensing,communication and ultrafast imaging.关键词
