Enhancing Thermoelectric Properties of Si80Ge20 Alloys Utilizing the Decomposition of NaBH4 in the Spark Plasma Sintering Process

The thermoelectric properties of spark plasma sintered, ball-milled, p-type Si80Ge20-(NaBH4)x (x = 0.7,1.7 and 2.7), and Si80Ge20B1.7-y-(NaBH4)y (y = 0.2 and 0.7) samples have been investigated from 30 K to 1100 K. These samples were prepared by spark plasma sintering of an admixture of Si, Ge, B an...
