In the last sentence of the abstract, “1000 °C” is incorrect:
“A figure of merit of zT = 0.5 +/- 0.09 at 450 °C and a peak zT of 0.8 +/- 0.15 at 1000 °C could be achieved for a nanostructured, 0.8% phosphorus-doped Si80Ge20 alloy without any further optimization.”
The correct temperature is 800 °C.
