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…

Electron-phonon couplings inherent in polarons drive exciton dynamics in two-dimensional metal-halide perovskites

Félix Thouin, Ajay Ram Srimath Kandada, David A. Valverde-Chávez +6

We report on the exciton formation and relaxation dynamics following photocarrier injection in a single-layer two-dimensional lead-iodide perovskite. We probe the time evolution of…

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…

Valley and spin dynamics in monolayer MoS

S. Dal Conte, F. Bottegoni, E. A. A. Pogna +10

Valleytronics targets the exploitation of the additional degrees of freedom in materials where the energy of the carriers may assume several equal minimum values (valleys) at non-e…
