For this study, we developed a thermal conductivity, κ, measurement system using 3ω method. We checked the system accuracy by measuring κ for a glass substrate (1737; Corning). Conventional evaporated aluminum wire and ink-jet printed silver wire were used as sensor wires. The system realized a κ measurement of glass within 10 % error. We estimated κ of aggregated p-type (Bi1-x Sb x )2Te 3 particles using a two heat flow model. The estimated thermal conductivity of the sample κ sample are 0.06-0.27 WK -1 m-1, which is smaller than the bulk value.
