Electronic structure and transport in materials with flat bands: 2D materials and quasicrystals
Guy Trambly de Laissardière, Somepalli Venkateswarlu, Ahmed Missaoui +9
In this review, we present recent works on materials whose common point is the presence of electronic bands of very low dispersion, called "flat bands", which are due to specific a…
Exciton dissociation in organic solar cells: An embedded charge transfer state model
Jouda Jemaa Khabthani, Khouloud Chika, Alexandre Perrin +1
Organic solar cells are a promising avenue for renewable energy, and our study introduces a comprehensive model to investigate exciton dissociation processes at the donor-acceptor…
Electronic structure and conductivity in functionalized multilayer black phosphorene
Jouda Jemaa Khabthani, Khouloud Chika, Ghassen Jemaï +2
Phosphorene and its components are highly reactive to oxygen when exposed to ambient conditions due to the presence of lone pairs of electrons on phosphorus atoms. Functionalizatio…
Model for the dynamics of carrier injection in a band with polaronic states: Application to exciton dissociation in organic solar cells
Khouloud Chika, Alexandre Perrin, Jouda Jemaa Khabthani +4
We develop a quantum model for the dynamics of carrier injection in a band that presents a strong carrier-vibration coupling. This coupling modifies the spectral density of the ban…
