New publication

Aihui and Yao’s work entitled “Ligand-Driven Grain Engineering of High Mobility Two-Dimensional Perovskite Thin-Film Transistors” has been published in JACS. We demonstrate field-effect transistors of a novel 2D OSiP with hole mobility approaching 10 cm2 V–1 s–1 with ON/OFF current ratios of ∼106 and excellent stability and reproducibility. Great collaboration with Prof. M. Ashraf Alam group and many others. Congratulations! Read the story here.

New postdocs

The group warmly welcomes two new postdoc fellows Dr. Yoon Ho Lee and Dr. Jiaonan Sun joining us. Dr. Lee received his PhD in Chemical Engineering from POSTECH with Prof. Joon Hak Oh. He will be co-advised by Prof. Dou and Prof. Mei on perovskite solar cells. Dr. Jiaonan Sun received her PhD in Chemistry from Ohio State University with Prof. Yiying Wu. She will work on developing novel and stable OSiPs for solar cells and LEDs. Welcome to the group. Look forward to working together!

New grants

The group receives new funding supports from Department of Energy Office of Basic Energy Sciences (with Prof. Libai Huang group) working on exciton and spin transports in 2D perovskites and National Science Foundation Division of Electrical, Communications and Cyber Systems (with Prof. Hanwei Gao at Florida State Univ.) working on perovskite LEDs. Thanks DOE and NSF for the supports!
