Excitonic States in Semiconducting Two-dimensional Perovskites
Alejandro Molina-Sánchez
Hybrid organic/inorganic perovskites have emerged as efficient semiconductor materials for applications in photovoltaic solar cells with conversion efficiency above 20 \%. Recent e…
Exciton-phonon coupling in the UV absorption and emission spectra of bulk hexagonal boron nitride
Fulvio Paleari, Henrique P. C. Miranda, Alejandro Molina-Sánchez +1
We present an \textit{ab initio} method to calculate phonon-assisted absorption and emission spectra in the presence of strong excitonic effects. We apply the method to bulk hexago…
Direct observation of intravalley spin relaxation in single-layer WS
Z. Wang, A. Molina-Sanchez, P. Altmann +12
In monolayer Transition Metal Dichalcogenides (TMDs) the valence and conduction bands are spin split because of the strong spin-orbit interaction. In tungsten-based TMDs the spin-o…
Inter- and intra-layer excitons in MoS/WS and MoSe/WSe heterobilayers
E. Torun, A. Molina-Sánchez, H. P. C. Miranda +1
Accurately described excitonic properties of transition metal dichalcogenide heterobilayers (HBLs) are crucial to comprehend the optical response and the charge carrier dynamics of…
