Effective Refractive-Index Approximation: A Link between Structural and Optical Disorder of Planar Resonant Optical Structures
Žarko Gačević, Nenad Vukmirović
We provide detailed insights into a link between structural and optical disorder of resonant optical structures, in particular, distributed Bragg reflectors (DBRs) and resonant mic…
Identification of Ultrafast Photophysical Pathways in Photoexcited Organic Heterojunctions
Veljko Janković, Nenad Vukmirović
The exciton dissociation and charge separation occurring on subpicosecond time scales following the photoexcitation are studied in a model donor/acceptor heterojunction using a ful…
Electron-phonon coupling in crystalline organic semiconductors: Microscopic evidence for nonpolaronic charge carriers
Nenad Vukmirovic, C. Bruder, Vladimir M. Stojanovic
We consider electron(hole)-phonon coupling in crystalline organic semiconductors, using naphthalene for our case study. Employing a first-principles approach, we compute the change…
Non-adiabatic molecular dynamics simulation for carrier transport in a molecular monolayer
Junfeng Ren, Nenad Vukmirovic, Lin-Wang Wang
We present a new approach to carry out non-adiabatic molecular dynamics to study the carrier mobility in an organic monolayer. This approach allows the calculation of a 4802 atom s…
Overlapping fragments method for electronic structure calculation of large systems
Nenad Vukmirović, Lin-Wang Wang
We present a method for the calculation of electronic structure of systems that contain tens of thousands of atoms. The method is based on the division of the system into mutually…
Polaronic signatures and spectral properties of graphene antidot lattices
Vladimir M. Stojanovic, Nenad Vukmirovic, C. Bruder
We explore the consequences of electron-phonon (e-ph) coupling in graphene antidot lattices (graphene nanomeshes), i.e., triangular superlattices of circular holes (antidots) in a…
