title = "Experimenting with hot isostatically pressed (HIP) nano grained bismuth-telluride-based alloys",
abstract = "Hot Isostatic Pressing (HIP) is was used for compaction of nano grained bismuth-telluride samples and results were compared to Spark Plasma Sintered (SPS) samples of the same materials. The powders were essentially the same as presented by Vasilevskiy1 et al, 2010. The (BixSb1-x)2(TeySe1-y)3 thermoelectric alloys studied in this article were produced by mechanical alloying under an inert atmosphere. The p-type alloy composition corresponds to x = 0.2, y = 1 and for the n-type material x = 0.95, y = 0.95. For HIP treatment the n- and p-type powders were encapsulated in copper cylinders under protective argon atmosphere. The HIP temperature was kept low to avoid excess grain growth of the materials. The electrical conductivity, carrier mobility, carrier concentration and Seebeck coefficient of HIP and SPS compacted materials were measured and compared.",
