High power density energy harvesting devices based on the anomalous Nernst effect of Co/Pt magnetic multilayers
Guillermo Lopez-Polin, Hugo Aramberri, Jorge Marques-Marchan +4
The anomalous Nernst effect (ANE) is a thermomagnetic phenomenon with potential applications in thermal energy harvesting. While many recent works studied the approaches to increas…
Strain control of hybridization between dark and localized excitons in a 2D semiconductor
Pablo Hernández López, Sebastian Heeg, Christoph Schattauer +8
Mechanical strain is a powerful tuning knob for excitons, Coulomb-bound electron-hole complexes dominating optical properties of two-dimensional semiconductors. While the strain re…
Mechanically-tunable bandgap closing in 2D graphene phononic crystals
Jan N. Kirchhof, Kirill I. Bolotin
We present a tunable phononic crystal which undergoes a phase transition from mechanically insulating to mechanically transmissive (metallic). Specifically, in our simulations for…
Nanomechanical spectroscopy of 2D materials
Jan N. Kirchhof, Yuefeng Yu, Gabriel Antheaume +7
We introduce a nanomechanical platform for fast and sensitive measurements of the spectrally-resolved optical dielectric function of 2D materials. At the heart of our approach is a…
