    Thermoelectric figure of merit and thermal conductivity of type-l clathrate alloy nanowires

    Clathrates based on Si and Ge have very low lattice thermal conductivity (~1 W/m-K). This value can potentially be further reduced by alloying and nano-structuring. In this work, the thermal conductivity of Si...

    Ab initio lattice thermal conductivity of bulk and thin-film α-AI2O3

    The thermal conductivities (κ) of bulk and thin-film α-AI2O3 are calculated from first principles using both the local density approximation (LDA) and the generalized gradient approximation (GGA) to exchange and ...
