Hysteretic phononic band structures arising from martensitic phase transformations
R. Esquivel-Sirvent, B. Manzanares-MartÃnez, J. Manzanares-MartÃnez
Thermal tuning of phononic crystals typically treats each constituent's elastic modulus as a single-valued function of temperature. Here we show that when one constituent undergoes…

Processing-Dependent Near-Field Radiative Heat Transfer at Au/SiC Interfaces
A. Márquez, R. Esquivel-Sirvent
Thermal annealing is a widely used thin-film processing technique for modifying interfacial optical losses and electronic scattering in plasmonic materials. Here, we investigate ho…
