Abstract
Two-dimensional (2D) lead halide perovskites (LHPs) are highly attractive for fabricating thin-film transistors (TFTs), but it remains a challenge for 2D LHP TFTs to work at room temperature (RT). Here, we present a protocol for fabricating 2D LHP TFTs that operate well at RT and exhibit high bias-stress stability and storage stability. We describe steps for preparing materials and equipment followed by fabrication of devices. We then detail measurement of device output characteristics and extraction of performance parameters. For complete details on the use and execution of this protocol, please refer to Qiu et al. (2023).1.
