Origins of Pressure-Enhanced Thermal Transport in Organic Semiconductors
Lukas Legenstein, Sandro Wieser, Michele Simoncelli +1
While pressure is known to dramatically alter the electronic properties of organic semiconductors, its impact on their thermal conductivity remains poorly understood. We combine ma…
Analyzing Heat Transport in Crystalline Polymers in Real and Reciprocal Space
Lukas Reicht, Lukas Legenstein, Sandro Wieser +1
Heat transport can be modelled with a variety of approaches in real space (using molecular dynamics) or in reciprocal space (using the Boltzmann transport equation). Employing two…
Heat transport in crystalline organic semiconductors: coexistence of phonon propagation and tunneling
Lukas Legenstein, Lukas Reicht, Sandro Wieser +2
Understanding heat transport in organic semiconductors is of fundamental and practical relevance. Therefore, we study the lattice thermal conductivities of a series of (oligo)acene…
Combining Brillouin spectroscopy and machine learned interatomic potentials to probe mechanical properties of metal organic frameworks
Florian P. Lindner, Nina Strasser, Martin Schultze +6
The mechanical properties of metal-organic frameworks (MOFs) are of high fundamental and also practical relevance. A particularly intriguing technique for determining anisotropic e…
Machine learned Force-Fields for an ab-initio Quality Description of Metal-Organic Frameworks
Sandro Wieser, Egbert Zojer
Metal-organic frameworks (MOFs) are an incredibly diverse group of highly porous hybrid materials, which are interesting for a wide range of possible applications. For a reliable d…
Identifying the Bottleneck for Heat Transport in Metal-Organic Frameworks
Sandro Wieser, Tomas Kamencek, Johannes P. Dürholt +3
Controlling the transport of thermal energy is key to most applications of metal-organic frameworks. Analyzing the evolution of the effective local temperature, the interfaces betw…
