“…1(d) we show that while the thermal conductivity systematically decreases with increasing aperiodicity, the maximum is observed even in the presence of moderate disorder at D ¼ 2-3. Indeed, such emergence of a thermal conductivity maximum was recently discovered experimentally [19] and through a Green's function based elastic model [20] at cryogenic temperatures in GaAs=AlAs superlattices with interfacially incorporated ErAs nanoparticles. Here, however, we demonstrate the effect in purely binary layered systems.…”

“…The phenomenon has been attributed to Anderson localization [18], originating from the destructive interference of coherent phonons and consequently quenching wave transport under structural disorder. Indeed, recent experiments [19] and numerical studies [20] on nanoparticle embedded SLs have shown evidence of Anderson localization of thermal phonons at low temperatures. However, to this end, no studies have been carried out to explicitly elucidate the spectral features of phonon localization in aperiodic SLs under anharmonic interactions.…”
