Abstract：

2D　lead　halide　perovskites　(LHPs)　are　highly　attractive　for　fabrication　of　thin-film　transistors　(TFTs)　due　to　their　promising　charge　transport　properties,　mitigated　ion　migration　effect,　and　high　stability.　However,　thus　far　there　have　been　no　reports　of　2D　LHP　TFTs　that　can　operate　well　at　room　temperature.　Herein,　we　report　a　simple　device　fabrication　strategy　for　2D　LHP　TFTs.　2D　LHP　TFTs　are　successfully　obtained　via　a　low-temperature　solution　process,　and　they　show　mobility　approaching　10−2　cm2　V−1　s−1　and　an　on/off　ratio　of　about　104　with　negligible　hysteresis　at　room　temperature.　Moreover,　the　devices　feature　high　bias-stress　stability　and　storage　stability.　Additionally,　large-area　TFT　arrays　show　a　high　degree　of　uniformity　in　device　performance　and　exhibit　capability　for　photodetection　imaging.　This　study　provides　solutions　to　address　the　challenges　in　device　fabrication　of　2D　LHP　TFTs　and　demonstrate　their　potential　for　practical　applications.　©　2022　The　Author(s)
