Dark states and delocalization: competing effects of quantum coherence on the efficiency of light harvesting systems
Zixuan Hu, Gregory S. Engel, Fahhad H. Alharbi +1
Natural light harvesting systems exploit electronic coupling of identical chromophores to generate efficient and robust excitation transfer and conversion. Dark states created by s…
An Efficient Descriptor Model for Designing Materials for Solar Cells
Fahhad H Alharbi, Sergey N Rashkeev, Fedwa El-Mellouhi +3
An efficient descriptor model for fast screening of potential materials for solar cell applications is presented. It works for both excitonic and non-excitonic solar cells material…
Kinetic Energy Density Functionals by Axiomatic Approach
Sabre Kais, Fahhad H Alharbi
An axiomatic approach is herein used to determine the physically acceptable forms for general -dimensional kinetic energy density functionals (KEDF). The resulted expansion capt…
Reduced work function of graphene by metal adatoms
Merid Legesse, Fedwa El Mellouhi, El Tayeb Bentria +4
In this paper, the work function of graphene doped by different metal adatoms and at different concentrations is investigated. Density functional theory is used to maximize the red…
