Size effect in thermoelectric materials
TL;DR: In this article, the size effect in low-dimensional thermoelectric materials is reviewed, including the quantum confinement effect on carriers, and the effect of phonon confinement and interface scattering on lattice thermal conductivity.

Stronger phonon scattering by larger differences in atomic mass and size in p-type half-Heuslers Hf$_{1-x}$Ti$_{x}$CoSb$_{0.8}$Sn$_{0.2}$
Xiao Yan,Weishu Liu,Haiyan Wang,Shuo Chen,Junichiro Shiomi,Hengzhi Wang,Dezhi Wang,Gang Chen,Zhifeng Ren +8 more
TL;DR: In this article, a lower thermal conductivity in p-type half-Heuslers was achieved when Ti is used to replace Zr, i.e., Hf1−xTixCoSb0.8Sn0.2, due to larger differences in the atomic mass and size between Hf and Ti.

Carbon Nanotubes as Optical Antennae
Krzysztof Kempa,J. Rybczynski,Zhongping Huang,Keith Gregorczyk,Andy Vidan,Brian R. Kimball,Joel B. Carlson,G. Benham,Yang Wang,Andrzej Herczynski,Zhifeng Ren +10 more
TL;DR: In this article, a simple wire antenna was shown to be a resonator of the external electromagnetic radiation, which is consistent with conventional radio antenna theory and simulations, by demonstrating that its directional radiation characteristics are in an excellent and quantitative agreement with conventional Radio antenna theory.
