The group warmly welcomes a new postdoc fellow Dr. Tareq Hossain joining us. Tareq received his PhD in Chemistry from University of Kentucky with Prof. Ken Graham. Tareq will work on perovskite solar cell and novel perovskite absorbers for hydrogen generation. Welcome to the group. Look forward to working together!

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.
