Abstract:We
show that engineering phonon scattering, such as through isotope
enrichment and temperature modulation, offers the potential to achieve
unconventional radiative heat transfer between two boron arsenide
bulks at the nanoscale, which holds promise in applications for nonlinear
thermal circuit components. A heat flux regulator is proposed, where
the temperature window for stabilized heat flux exhibits a wide tunability
through phonon scattering engineering. Additionally, we propose several
other nonlinear ther… Show more
