Phonon engineering in proximity enhanced superconductor heterostructures

Phonon engineering in proximity enhanced superconductor heterostructures

Abstract In this research, we tailor the phonon density of states (DOS) in thin superconducting films to suppress quasiparticle losses. We examine a model system of a proximity-enhanced three-layered Al/Nb/Al heterostructure and show that the local quantized phonon spectrum of the ultrathin Al cladd...
