Identifying incoherent mixing effects in the coherent two-dimensional photocurrent excitation spectra of semiconductors
Ilaria Bargigia, Elizabeth Gutiérrez-Meza, David A. Valverde-Chávez +3
We have previously demonstrated that in the context of two-dimensional (2D) coherent electronic spectroscopy measured by phase modulation and phase-sensitive detection, an \emph{in…
Frenkel biexcitons in hybrid HJ photophysical aggregates
Elizabeth Gutiérrez Meza, Ravyn Malatesta, Hongmo Li +9
Frenkel excitons, the primary photoexcitations in organic semiconductors that are unequivocally responsible for the optical properties of this materials class, are predicted to for…
Ultrafast correlated charge and lattice motion in a hybrid metal halide perovskite
Yang Lan, Benjamin J. Dringoli, David A. Valverde-Chavez +5
Hybrid organic-inorganic halide perovskites have shown remarkable optoelectronic properties (1-3), believed to originate from correlated motion of charge carriers and the polar lat…
Phonon coherences reveal the polaronic character of excitons in two-dimensional lead-halide perovskites
Félix Thouin, David A. Valverde Chávez, Claudio Quarti +6
Hybrid organic-inorganic semiconductors feature complex lattice dynamics due to the ionic character of the crystal and the softness arising from non-covalent bonds between molecula…
How optical excitation controls the structure and properties of vanadium dioxide
Martin R. Otto, Laurent P. René de Cotret, David A. Valverde-Chavez +5
We combine ultrafast electron diffraction and time-resolved terahertz spectroscopy measurements to unravel the connection between structure and electronic transport properties duri…
