Time-dependent framework for energy and charge currents in nanoscale systems
Thomas Lehmann, Alexander Croy, Rafael Gutiérrez +1
The calculation of time-dependent charge and energy currents in nanoscale systems is a challenging task. Nevertheless it is crucial for gaining a deep understanding of the relevant…
Enhanced thermoelectric figure of merit in polycrystalline carbon nanostructures
Thomas Lehmann, Dmitry A. Ryndyk, Gianaurelio Cuniberti
Grain boundaries are commonly observed in carbon nanostructures, but their influence on thermal and electric properties are still not completely understood. Using a combined approa…
Combined effect of strain and defects on the conductance of graphene nanoribbons
Thomas Lehmann, Dmitry A. Ryndyk, Gianaurelio Cuniberti
We investigate the combined influence of structural defects and uniaxial longitudinal strain on the electronic transport properties of armchair graphene nanoribbons using the numer…
Comparison of electron and phonon transport in disordered semiconductor carbon nanotubes
H. Sevincli, T. Lehmann, D. A. Ryndyk +1
Charge and thermal conductivities are the most important parameters of carbon nanomaterials as candidates for future electronics. In this paper we address the effects of Anderson t…
