“…Thermal conductivities in superlattices such as GaAs/Al͑Ga͒As, [15][16][17][18] InAs/AlSb 19 and InP/InGaAs 20 , are much lower than the predictions based on Fourier law and bulk thermal conductivity values of their constituents, and tend to be even lower than in alloys with the same average composition. Various models based on minigap scattering, 21 the Boltzmann transport equation, 22,23 and phonon group velocity reduction 24 -26 have been developed to explain this trend.…”

A differential 3 technique is employed to determine the thermal conductivity of the AlAs 0.07 Sb 0.93 ternary alloy, the Al 0.9 Ga 0.1 As 0.07 Sb 0.93 quaternary alloy, and an (AlAs) 1 /(AlSb) 11 digital-alloy superlattice. Between 80 and 300 K, the thermal conductivities for all three samples are relatively insensitive to temperature. The thermal conductivity of the (AlAs) 1 /(AlSb) 11 superlattice is smaller than that of the AlAs 0.07 Sb 0.93 ternary alloy, but much larger than the predictions of a model for phonon transport across the superlattice interfaces.

“…Some experimental and theoretical works [40][41][42][43][44] have been carried out to study the effects of interface and superlattice period on thermal conductivity of various kinds of superlattice structures. Results show that superlattice structures are an efficient way to get ultra low thermal conductivity.…”

Ultralow Thermal Conductivity of Isotope-Doped Silicon Nanowires

The thermal conductivity of silicon nanowires (SiNWs) is investigated by molecular dynamics (MD) simulation. It is found that the thermal conductivity of SiNWs can be reduced exponentially by isotopic defects at room temperature. The thermal conductivity reaches the minimum, which is about 27% of that of pure 28 Si NW, when doped with fifty percent isotope atoms. The thermal conductivity of isotopic-superlattice structured SiNWs depends clearly on the period of superlattice. At a critical period of 1.09 nm, the thermal conductivity is only 25% of the value of pure Si NW. An anomalous enhancement of thermal conductivity is observed when the superlattice period is smaller than this critical length. The ultra-low thermal conductivity of superlattice structuredSiNWs is explained with phonon spectrum theory.

“…The thermal conductivity of skutterudite thin films has not been studied extensively. On the other hand, increasing experimental evidence has been reported on the large thermal conductivity reduction in various superlattices including GaAs/AlAs, [10][11][12][13][14] Si/Ge, [15][16][17] and Bi 2 Te 3 /Sb 2 Te 3 . 18 It is of both fundamental and practical interests to examine the thermal conductivity of skutterudite thin films and their superlattices.…”

Experimental results on the temperature-dependent cross-plane thermal conductivity of skutterudite thin films are presented. The films examined include IrSb3, CoSb3, and Ir0.5Co0.5Sb3 single layers, and IrSb3/CoSb3 superlattices that are grown by pulsed-laser deposition. A differential 3ω method is used to measure the cross-plane thermal conductivity of these films from 80 to 300 K. The experimental results show a significant reduction in their thermal conductivity values compared to those of their corresponding bulk samples reported in literature. Possible mechanisms contributing to the thermal conductivity reduction are discussed.
