Time-domain observation of interlayer exciton formation and thermalization in a MoSe/WSe heterostructure
Veronica R. Policht, Henry Mittenzwey, Oleg Dogadov +11
Vertical heterostructures (HS) of transition metal dichalcogenides (TMDs) host interlayer excitons (ILX), with electrons and holes residing in different layers. With respect to the…
Calculated optical properties of BTTzR donor molecule and its derivatives
Giuseppe Maria Paternò, Andrea Farina, Francesco Scotognella
In this work, we study the light absorption properties of a novel molecule (BTTzR) and its more extended derivatives, which hold promise as electron-donor material in organic solar…
Optical properties of recent non-fullerene molecular acceptors for bulk heterojunction solar cells
Andrea Farina, Giuseppe M. Paternò, Francesco Scotognella
For many years the faith of organic photovoltaics has been linked to the one of fullerene, since fullerene has been considered the electron-acceptor of choice in bulk heterojunctio…
The ultrafast onset of exciton formation in 2D semiconductors
Chiara Trovatello, Florian Katsch, Nicholas J. Borys +11
The equilibrium and non-equilibrium optical properties of single-layer transition metal dichalcogenides (TMDs) are determined by strongly bound excitons. Exciton relaxation dynamic…
