Impact of nuclear effects on the ultrafast dynamics of an organic/inorganic mixed-dimensional interface

M Jacobs, K Fidanyan, M Rossi, C Cocchi - Electronic Structure, 2024 - iopscience.iop.org
Electron dynamics at weakly bound interfaces of organic/inorganic materials are easily
influenced by large-amplitude nuclear motion. In this work, we investigate the effects of …
