Charge Transport Framework for Crystalline pi-Conjugated Materials
Nisarg Trivedi, Maximilian F. X. Dorfner, Michel Panhans +1
Quantitative charge-transport modelling in crystalline pi-conjugated polymers requires an electronic representation that captures extended conjugation and material-specific electro…
Interplay between Electronic Structure, Chemical Bonding, and Lattice Symmetry in Bismuth Vanadate
Philip Schwinghammer, Franziska S. Hegner, Frederico P. Delgado +5
Bismuth vanadate (BiVO) is a prototypical oxide photocatalyst that occurs in both tetragonal and monoclinic scheelite phases with markedly different photocatalytic and photoele…
Ultrafast photo-thermoelectric currents in graphene junctions in the mid-infrared
Nina Pettinger, Michel Panhans, Johannes Schmuck +8
Graphene is widely recognized for its ultrafast and broadband photocurrent response, but whether the broadband ultrafast characteristics are preserved at mid-infrared wavelengths w…
Hall Transport in Organic Semiconductors
Michel Panhans, Frank Ortmann
We establish a universal theory to understand quasiparticle Hall effects and transverse charge-carrier transport in organic semiconductors. The simulations are applied to organic c…
Efficient Time-Domain Approach for Linear Response Functions
Michel Panhans, Frank Ortmann
We derive the general Kubo formula in a form that solely utilizes the time evolution of displacement operators. The derivation is based on the decomposition of the linear response…
