Thermoelectric　semiconductors　based　on　GeTe　has　been　proved　to　be　an　important　materials　for　converting　waste　heat　into　electricity.　In　this　study,　we　demonstrate　an　enhancement　of　thermoelectric　performance　for　p-type　Ge0.9Sb0.1Te1+x　by　a　unique　melt　spinning　method　combined　with　hot　pressing　(MS-HP),　through　which　increased　Seebeck　coefficients　and　reduced　thermal　conductivities　are　achieved　simultaneously.　Moreover,　the　MS　technique　greatly　gives　rise　to　a　variety　of　microstructures,　such　as　the　fine　Ge　precipitates,　twins　and　nano-domains,　all　of　which　contribute　to　the　significantly　reduced　thermal　conductivities.　Finally,　the　Ge0.9Sb0.1Te1.03　reaches　a　maximum　zT　value　of　similar　to　1.9　at　760　K　and　a　giant　average　zT　of　similar　to　1.2　between　300　K　and　820　K,　which　is　comparable　to　the　reported　results　for　GeTe　based　materials.　Combined　with　the　rapid　fabrication,　Ge-0.9Sb0.1Te1+x　prepared　by　melt　spinning　process　is　an　attractive　p-type　material　for　thermoelectric　power　generation　application.　(C)　2018　Published　by　Elsevier　B.V.
