New around of the prestigious Lillian Gilbreth Postdoc Fellowship has been announced! If you are interested in joining us and working in a multidisciplinary research environment, please apply at: https://engineering.purdue.edu/Engr/Research/GilbrethFellowships

We are excited to have a new postdoc fellow Dr. Shuchen Zhang to join the group. Shuchen got his PhD from Peking University in Physical Chemistry. Before joining Purdue, he spent one year as a postdoc fellow with Prof. Gabor Somorjai at UC Berkeley. Welcome to the group and look forward to working together! 

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!

Our review paper on 2D hybrid perovskites incorporating semiconducting organic building blacks has been published in Materials Chemistry Frontiers. This is for a special issue Celebrating Prof. Fred Wudl’s 80th Birthday. Congratulations!

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.
