Wenhao and Jeong Hui’s paper on the molecular templating of layered halide perovskite nanowires have been published in Science. Congratulations!
Dr. Phil Szuromi’s summary: “A templating method enables the growth of two-dimensional metal-halide perovskite nanowires that exhibit polarized photoluminescence and enable low-loss waveguiding. Shao et al. grew nanowires of (BrCA3)2PbBr4, where BrCA3 is 2-(2-bromo-5-carboxyphenoxy)ethan-1-aminium. The carboxylic acid group of BrCA3 inhibited the growth of all crystal facets except [110], which led to one-directional growth. The nanowires also achieved efficient light amplification, with a threshold of less than 20 microjoules per square centimeter.” Read the full story here. The story is highlighted by Purdue and many news outlets.
