Abstract Flexible and curved infrared focal plane arrays (FPAs) are attracting great interest with increasing demand for sensitive, low-cost and scalable cameras that can achieve wide field of view, low aberrations, and simple imaging optics. The widespread use of such flexible detectors, however, is still limited by the brittle nature of the dominant infrared epitaxial semiconductors like HgCdTe, InSb, and InGaAs, together with their high cost for both growth and processing. In contrast, colloidal quantum dots (CQDs) have inspired various optoelectronic devices benefitting from their solution-processability, mechanical flexibility and wide spectral tunability over important atmospheric windows from short-wave infrared (SWIR, 1.5 – 2.5 µm), mid-wave infrared (MWIR, 3 – 5 µm) to long-wave infrared (LWIR, 8–14 µm). In this review, we summarize the recent progress of CQDs-based infrared optoelectronics regarding device configuration, photodetection properties, device flexibilities and some potential routes leading to infrared imaging FPA.

开发具有 HgTe 胶体量子点的柔性弯曲红外探测器

摘要 随着对能够实现宽视场、低像差和简单成像光学的灵敏、低成本和可扩展相机的需求不断增加，柔性和弯曲的红外焦平面阵列 (FPA) 引起了极大的兴趣。然而，这种柔性探测器的广泛使用仍然受到主要红外外延半导体（如 HgCdTe、InSb 和 InGaAs）的脆性以及它们的生长和加工成本高的限制。相比之下，胶体量子点 (CQD) 启发了各种光电器件，这些器件受益于它们的溶液可加工性、机械灵活性和宽光谱可调性，它们在短波红外（SWIR，1.5 – 2.5 µm）、中波红外（ MWIR，3 – 5 µm）到长波红外（LWIR，8–14 µm）。在这次审查中，
