基于类钙钛矿/有机异质结的光敏场效应管制备与性能研究摘要有机半导体材料因轻、廉、柔性兼容等优点，广泛用于光电子领域。基于光诱导效应的光敏场效应晶体管可放大光电流，是实现全有机图像传感器的前景器件。由于铅基钙钛矿的毒性和对水、热、光等因素的敏感性，发展非铅稳定的钙钛矿材料已成为该领域的研究热点。本文基于铯秘碘钙钛矿分别和C8、CuP℃、并五苯的异质结有机光敏场效应管分别研究其光照和非光照条件下的器件输出特性曲线。通过对比有机物所制作的场效应管和有机物和铯铋碘的所制作的有机光敏场效应管的输出特性曲线，得出铯铋碘类钙钛矿和有机物所制作的有机光敏场效应管的优劣。关键词光敏场效应管：类钙钛矿：有机异质结Preparation and performance ofphotosensitive FETs based onperovskite-like/organic heterojunctionsABSTRACTOrganic semiconductor materials are widely used in optoelectronics because of theiradvantages of lightness,low cost and flexible compatibility.Photosensitive field-effecttransistors based on light-induced effects amplify photocurrent and are promising devicesfor all-organic image sensors.Due to the toxicity and sensitivity of lead-based perovskitesto water,heat,light and other factors,the development of non-lead-stabilized perovskitematerials has become a research hotspot in this field.In this paper,the output characteristiccurves of devices under light and non-illumination conditions were studied based oncesium-bismuth iodine perovskite and heterojunction organic photosensitive FETs of C8,CuPc,and pentabenzene,respectively.By comparing the output characteristic curves of thefield effect tube made of organic matter and the organic photosensitive FET made oforganic matter and cesium bismuth iodine,the advantages and disadvantages of organicphotosensitive FETs made of cesium bismuth iodine perovskite and organic matter areobtained.Key words photoFET;Perovskite-like;Organic heterojunction目录摘要ABSTRACT目录…Π引言.l第一章光敏场效应管的研究进展21.1.场效应管的发展.21.2.钙钛矿有机光敏场效应管的发展.21.3。光敏场效应管的原理..31.4.ph0OFET的结构..4第二章类钙钛矿材料的研究进展.52.1.类钙钛矿材料的发展.52.2.类钙钛矿材料的优点…52.3.铯铋碘材料的研究进展.6第三章基于铯铋碘和并五苯的异质结光敏场效应管的制备与研究.73.1.器件的制备.73.1.1.硅片以及掩模版的清洗.73.1.2.器件的制备…。73.2.器件性能测试10第四章总结与展望.14参考文献16致谢.18Ⅲ
