Nitrogen-vacancy magnetometry of individual Fe-triazole spin crossover nanorods

Suvechhya Lamichhane, Kayleigh A McElveen, Adam Erickson +7

[Fe(Htrz)2(trz)](BF4) (Fe-triazole) spin crossover molecules show thermal, electrical, and optical switching between high spin (HS) and low spin (LS) states, making them promising…

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…

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…
