Liquid-like Free Carrier Solvation and Band Edge Luminescence in Lead-Halide Perovskites
Yinsheng Guo, Omer Yaffe, Trevor D. Hull +3
We report a strongly temperature dependent luminescence Stokes shift in the electronic spectra of both hybrid and inorganic lead-bromide perovskite single crystals. This behavior s…
Controlled Electrochemical Intercalation of Graphene/h-BN van der Waals Heterostructures
S. Y. Frank Zhao, Giselle A. Elbaz, D. Kwabena Bediako +11
Electrochemical intercalation is a powerful method for tuning the electronic properties of layered solids. In this work, we report an electro-chemical strategy to controllably inte…
Interplay between organic cations and inorganic framework and incommensurability in hybrid lead-halide perovskite CH3NH3PbBr3
Yinsheng Guo, Omer Yaffe, Daniel W. Paley +6
Organic-inorganic coupling in the hybrid lead-halide perovskite is a central issue in rationalizing the outstanding photovoltaic performance of these emerging materials. Here we co…
Coulomb engineering of the bandgap in 2D semiconductors
Archana Raja, Andrey Chaves, Jaeeun Yu +13
The ability to control the size of the electronic bandgap is an integral part of solid-state technology. Atomically-thin two-dimensional crystals offer a new approach for tuning th…
Local polar fluctuations in lead halide perovskite crystals
Omer Yaffe, Yinsheng Guo, Liang Z. Tan +11
Hybrid lead-halide perovskites have emerged as an excellent class of photovoltaic materials. Recent reports suggest that the organic molecular cation is responsible for local polar…
Intrinsic lineshape of the Raman 2D-mode in freestanding graphene monolayers
Stéphane Berciaud, Xianglong Li, Han Htoon +3
We report a comprehensive study of the two-phonon inter-valley (2D) Raman mode in graphene monolayers, motivated by recent reports of asymmetric 2D-mode lineshapes in freestanding…
