Fengyu's paper on "Gap States in Methylammonium Lead Halides: The Link to Dimethylsulfoxide?", in collaboration with the group of Prof.Lynn Loo, appears on-line in Advanced Materials.

The paper entitled "n-Doping of a Low-Electron-Affinity Polymer Used as an Electron-Transport Layer in Organic Light-Emitting Diodes" is the product of a collaboration with the groups of Seth Marder, Georgia Tech., and Barry Rand, Princeton.

The paper entitled "Ultraviolet Photoemission Spectroscopy and Kelvin-probe Measurements on Metal Halide Perovskite: Advantages and Pitfalls" outlines issues related to the proper treatment of UPS data to investigate the low density of states at the top of the valence band, as well as potential degradation of the material in vacuum under…

Congratulations to Fengyu for receiving a School of Engineering and Applied Science Award for Excellence! This award is given to SEAS advanced graduate students who have performed at the highest level as scholars and researchers. 

Fengyu's work on "Molecular reductant-induced control of a graphene-organic interface for electron injection", in collaboration with Georgia Tech and ben Gurion University, appears in the Sept. 10 special issue of Chemistry of Materials  

Xinjue completed her PhD in the Department of Chemistry, Columbia University, in the group of Prof. Xiaoyang Zhu.  Welcome Xinjue!

In collaboration with the group of Prof. Marc Baldo at MIT, Hannah determined energy level offsets at the tetracene-HfOxNy-Si interface, leading to the publication of the paper “Sensitization of silicon by singlet exciton fission in tetracene”, Nature 571, 90 (2019).  Congratulations Hannah!

The paper, entitled "Quantum Well Energetics of a n=2 Ruddlesden-Popper Phase Perovskite", is the product of a collaboration with the group of Jean-Luc Bredas.
