Congratulations to Dr. Ke Ma to be awarded the prestigious Lillian Gilbreth Postdoc Fellowship. Ke received her PhD in Chemical Engineering from the University of Colorado Boulder in December 2017 and her BS degree in Chemical Engineering & Technology from Zhejiang University. Ke will be working with the Dou, Mei, and Boudouris groups at Purdue. We look forward to welcoming Dr. Ma in this August.
The group receives a seed grant from Purdue Process Safety and Assurance Center (P2SAC) for developing safer materials and processing in printed electronics. Thanks for the support and congratulations to the group!
Enzheng and Shibin’s paper about 2D perovskite edge states is published in ACS Nano. Congratulations!
We report the formation mechanism and the dynamic nature of edge states on the exfoliated 2D halide perovskites thin crystals. In contrast to other 2D materials, the edge states in 2D perovskites are extrinsic and composed of multiple low energy states due to interaction with moisture. We demonstrate that the charge carriers on the dynamically formed edge states are not only long-lived, but also highly mobile and can be conducted along the edges effectively with high mobilities of 5.4-7.0 cm2V-1s-1. This work provides significant insights on the origin of the edge states in 2D perovskites and provides routes to manipulate their optical and electrical properties through controlling their edges.
Dr. Dou is selected in the MIT Technology Review Innovators Under 35 China list for the work in new photovoltaic technologies.
Aidan and Blake pass their qualifier exams. Congratulations!
The group receives funding from Office of Naval Research (ONR). Dr. Dou is recognized as one of the 2019 ONR Young Investigator Award Recipients. Thanks for the support and congratulations to all!
