Going beyond this limitation has been a long-standing challenge in the development of infrared detectors. This paper proposes to break this limitation by creating a narrow photoresponse band with a high peak responsivity to reject the background radiation and enhance the responsivity to the target with characteristic emission lines. This scheme is numerically demonstrated in a dimerized grating integrated quantum well infrared photodetector, based on critical coupling with a Brillouin zone folding induced quasi-bound state in the continuum (BIC). The asymmetric deformation of the grating structure folds the photonic band and generates a quasi-BIC with a tunable high radiation <i>Q</i> factor (<i>Q_R</i>) at the Γ point. By reducing the doping concentration of the quantum wells for a high absorption <i>Q</i> factor (<i>Q_A</i>) and tuning the <i>Q_R</i> to make <i>Q_R</i> = <i>Q_A</i> for critical coupling, a narrowband photoresponse with a high peak responsivity is achieved and the background-limited specific detectivity of 4.55 × 10¹² cm Hz^1/2 W⁻¹ is obtained for a 2π field of view, surpassing the ideal-photoconductor limit by 92 times.</p>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 35","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PIDS leads to the formation of 2D perovskite PEA₂MA_x-1Pb_xI_3x+1 (PEA = phenylethylamine, MA = methylamine) within MAPbI₃ PMN, which not only prevents water and oxygen erosion to thwart PMN degradation but also inhibits the transport of dark state carriers to reduce dark current.

Achieving a specific diffuse scattering is one example and this often requires electrically large and diverse AEM arrays.
