AbstractTwo-dimensional (2D) metal halide perovskites have shown great potential in high performance optoelectronic applications due to their intrinsic quantum well structure, enhanced moisture- and photo-stability. Unfortunately, there is still no effective method to produce large-size 2D hybrid perovskite single crystals, and consequently there is lack of research on its optoelectronic applications. Herein, we report the utilization of a controlled evaporation process to grow well-defined large-size (>200 mm(2)) 2D (PEA)(2)PbBr4 (C6H5CH2CH2NH3+, PEA(+)) single crystals. Upon careful examination of the crystal growth kinetics, it was found that the optimum temperature for the growth of (PEA)(2)PbBr4 single crystal wafer was 23 +/- 0.5 degrees C. The wafers that were harvested showed high mu-tau () product, superior environmental stability and irradiation resistance. Furthermore, an array of planar-type UV photodetectors were designed and fabricated with extremely low dark current (approximate to 10(-13) A), large ON/OFF current ratio (approximate to 10(5)), very high specific detectivity (approximate to 10(13) cm Hz(1/2) W-1) and fast response rate (approximate to 0.4 ms). All the above performance data are among the best achieved compared to those of the state-of-the-art materials including ZnO, TiO2 and GaN in the field. It makes us believe that the availability of these materials may pave the way for ultrafast optical computing and optical communications.
