Just published in Nature Communications: “Intrinsic lattice anharmonicity in hybrid perovskite nanocrystals”

20.04.2021

Tushar Debnath generated and detected coherent phonons in organic-inorganic lead halide perovskite nanocrystals. Their dynamics reveal that in the case of bromide the organic molecule is stuck, whereas in the case of iodide it is free to rotate. To learn more how the organic molecule interacts with the lead-halide framework and how it influences its intrinsic lattice anharmonicity, have a look at our new paper just published in Nature Communications:

“Coherent Vibrational Dynamics Reveals Lattice Anharmonicity in Organic inorganic Halide Perovskite Nanocrystals” by T. Debnath, D. Sarker, H. Huang, Z.-K. Han, A. Dey, L. Polavarapu, S. V. Levchenko, J. Feldmann. Nat. Commun. 2021, DOI : 10.1038/s41467-021-22934-2.
