Preparation and thermoelectric properties of Bi2Te3-Bi2Se3 solid solutions

Bi2Te3−ySey (y = 0.0 − 0.6) solid solutions were prepared by encapsulated melting and hot pressing. The lattice constants decreased linearly with increasing Se content, which confirmed the successful…

Preparation and Thermoelectric Properties of Doped Bi2Te3-Bi2Se3 Solid Solutions

Since Bi2Te3 and Bi2Se3 have the same crystal structure, they form a homogeneous solid solution. Therefore, the thermal conductivity of the solid solution can be reduced by phonon scattering. The…
