The samples prepared via MG-HP were single-phased, had high relative densities (> 99%), and exhibited uniform morphologies. For a milling rate of 2.5 Hz, the minimum κphonon of MG-HP was 0.90 W m−1 K−1 and the average grain size was 0.47 µm. Furthermore, the grains produced by MG-HP and milled at 2.5 Hz comprised subgrains with a size of approximately 50 nm. The samples prepared using MA-HP showed higher theoretical relative densities. For a milling rate of 2.0 Hz, the minimum κphonon of MA-HP was 1.36 W m−1 K−1 and the average grain size was 0.52 µm. The electrical conductivity and Seebeck coefficient of MG-HP and MA-HP were similar to those of the p-type doped materials. Thus, the MG-HP process is an appropriate method for producing undoped PbTe with a high Seebeck coefficient and a low κphonon.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"© 2022.
