We are hosting a special issue in Frontiers in Energy Research with Prof. Aditya Mohite @ Rice Univ and Prof. Qi Chen @ Beijing Institute of Technology on “Two-Dimensional Halide Perovskite Nanomaterials for Solar Energy Conversion“. Welcome submissions to this special issue!
Dr. Enzheng Shi will join Westlake University in Hangzhou, China, as an assistant professor in School of Engineering this winter. Thank you for your great work in the past three years. Big congratulations and good luck with your future endeavor!
Aidan is selected for the HOPE workshop organized by NREL; Alan and Yiyuan are selected for the SURF program. Congratulations! (All these programs will be virtual this year)
Our collaborative work (with Prof. Yi Yu group @ShanghaiTech and Prof. Brett Savoie group @Purdue ) entitled “Two-dimensional halide perovskite lateral epitaxial heterostructures” has been published in Nature. Big congratulations!
Halide perovskites are attractive for applications such as solar cells, LEDs, detectors and lasers. Their inherently soft crystal lattice allows greater tolerance to lattice mismatch, making them promising for heterostructure formation and semiconductor integration. Here we report an effective strategy to substantially inhibit in-plane ion diffusion and enhanced stability in two-dimensional halide perovskites by incorporating rigid π-conjugated organic ligands. We demonstrate highly stable and tunable lateral epitaxial heterostructures, multiheterostructures and superlattices with near atomically sharp interfaces. These findings provide insights into the immobilization and stabilization of halide perovskite semiconductors and demonstrate a materials platform for complex and molecularly thin superlattices, devices and integrated circuits.
Aidan and Pilsun (P. Liao group)’s paper entitled “Structural Tunability and Diversity of Two‐Dimensional Lead Halide Benzenethiolate” has been published in Chemistry – A European Journal. Congratulations!
We welcome visiting students from Europe to apply for the Trans-Atlantic Visiting Engineer Research Scholarship Experience (TraVERSE) program that sponsored by College of Engineering of Purdue University!
Sheng-Ning passes his qualifier exam and now become a PhD candidate. Congratulations!
Dr. Dou is recognized as a Highly Cited Researcher 2019 in Cross Field by Web of Science (Clarivate Analytics).
Each year, the Web of Science Group identifies the world’s most influential researchers. In 2019, fewer than 6,300, or 0.1%, of the world’s researchers, across 21 research fields, have earned this exclusive distinction by the production of multiple highly-cited papers that rank in the top 1% by citations for field and year in Web of Science.
Our Nature Chemistry paper regarding the synthesis of organic-inorganic hybrid perovskite quantum wells is online now. Read the Nat Chem paper here.
Using this concept, we demonstrated highly stable lead-free perovskite thin film transistors with high charge carrier mobility. Read the JACS paper here.
