    Supporting Data for Mitigating Damage to Hybrid Perovskites Using Pulsed-Beam TEM
    (2021-01-08) VandenBussche, Elisah J; Flannigan, David J; Holmes, Russell J; Clark, Catherine P; vand0837@umn.edu; VandenBussche, Elisah; Flannigan Lab, CEMS Department, University of Minnesota
    Using a pulsed-beam transmission electron microscope, we discover a reduction in damage to methylammonium lead iodide (MAPbI3) as compared to conventional beams delivered at the same dose rates. This work provides insights into damage processes and durability in hybrid perovskites and also illustrates the viability of using pulsed-beam TEM to explore the associated molecular-level routes to degradation, analogous to laser-accelerated energetic pulsed electron beams and the study of damage to biomolecules, cells, and tissues in radiobiology. The data acquired in this experiment are released here to enable open access to published data in accordance with MRSEC data policies.

    The experimental and modeled resonance Raman and absorption dataset for pentacene polaritons measured at various angles taken in the Frontiera lab at the University of Minnesota in 2023
    (2025-02-24) Alam, Shahzad; Liu, Yicheng; Holmes, Russell J; Frontiera, Renee R; rrf@umn.edu; Frontiera, Renee R.; University of Minnesota Frontiera Research Lab
    This dataset contains resonance Raman measurements and angle-resolved reflectivity data for two optical cavities with pentacene layers of 27 nm and 39 nm thickness, as well as a 27 nm pentacene thin film at various angles. Additionally, it includes results from resonance Raman intensity analysis, comprising modeled absorption cross-section and Raman cross-section profiles for the same three systems.
