Thermodynamic performance bounds for radiative heat engines
, 2023 This paper discusses the performance limits of heat engines exchanging heat radiatively with a hot source while in thermal contact with a cold sink. Starting from solar energy conversion models, we derive power-versus-efficiency upper bounds for both ...

Monitoring the low doping regime in graphene using Raman 2D peak-splits: Comparison of gated Raman and transport measurements [PDF]
, 2019 Avoiding charge density fluctuations and impurities in graphene is vital for high-quality graphene-based devices. Traditional characterization methods require device fabrication and electrical transport measurements, which are labor-intensive and time ...

Investigating the Interplay between Spin-Polarization and Magnetic Damping in $\mathrm{Co}_{x}\mathrm{Fe}_{80-x}\mathrm{B}_{20}$ for Magnonics Applications [PDF]
For magnonics and spintronics applications, the spin polarization ($P$) of a transport current and the magnetic damping ($\alpha$) play a crucial role, e.g. for magnetization dynamics and magnetization switching applications.

Shaping THz emission spectra by using sub-wavelength nanopatterned spintronic THz emitters
, 2023 We show in theory and experiment that in periodically patterned spintronic THz emitters (STE), charge dynamics can modify the emission spectrum in a well-controlled way.
