## Description

- description: 'N-type Mg3Sb2 alloys show great potential for wasted heat energy harvesting
    due to their promising thermoelectric properties. In this work, we discover that
    doping transition element Ag into the n-type Mg3Sb2 alloy can effectively optimize
    the power factor and suppress the lattice thermal conductivity simultaneously.
    A high power factor of 19.6 μW cm−1 K−2 is obtained at 673 K owing to the increased
    electrical conductivity. At the same time, the lattice thermal conductivity is
    reduced to 0.50 W m-1 K-1 as a result of enhanced phonon scattering induced Ag
    atoms. These improvements lead to a peak figure of merit (ZT) of 1.64 at 673 K
    as well as a high average ZT of 1.27 is obtained from 323K to 673K. Furthermore,
    a thermoelectric single leg device with a competitive conversion efficiency of
    ~11% under a hot-side temperature of 673 K is fabricated successfully, suggesting
    an exceptional potential in the future application for in waste heat energy harvesting
    and thermoelectric power generation.    '
