Abstract
A series of polycrystalline Sn1−xNaxSe with x = 0.00, 0.02, 0.04 and 0.10 were fabricated using hydrothermal synthesis followed by evacuated-and-encapsulated sintering. The as-fabricated materials were characterized using powder x-ray diffraction and electronic transport. The resulting materials were single phase. Partial replacement of Na for Sn leads to a simultaneous increase of electrical conductivity and thermopower. The x = 0.04 sample has the largest power factor among the series of the samples. Upon partial replacement of Na for Sn, the power factor is significantly enhanced as compared to the undoped SnSe. The maximum ZT value of ∼0.4 was achieved for Sn0.96Na0.04Se at 550 K.
