Enhanced thermoelectric performance enabled by compositing ZrO2 in n-type SiGe alloy with low thermal conductivity
SiGe-based thermoelectric (TE) materials have gained increasing interests due to their low maintenance costs, environmental friendliness and long lifespan.

| description | SiGe-based thermoelectric (TE) materials have gained increasing interests due to their low maintenance costs, environmental friendliness and long lifespan. However, the intrinsically high thermal conductivity of Si-based materials also results in poor TE properties. In this investigation, a zirconia (ZrO
2
) composite strategy was applied to an n-type SiGe alloy, tremendously elevating its TE performance. After mechanical alloying and spark plasma sintering (SPS) processes, the ZrO

induced the formation of nanopores in the SiGe matrix via phosphorus adsorption. Moreover, such increase in porosity enhanced the phonon scattering and dramatically suppressed lattice thermal conductivity, from 2.83 to 1.59 W·m
