Weak electron–phonon coupling and enhanced thermoelectric performance in n-type PbTe–Cu₂Se via dynamic phase conversion

Weak electron–phonon coupling and enhanced thermoelectric performance in n-type PbTe–Cu₂Se via dynamic phase conversion

This study investigates Ga-doped n-type PbTe thermoelectric materials and the dynamic phase conversion process of the second phases via Cu2Se alloying. Introducing Cu2Se enhances its electrical transport properties while reducing its lattice thermal conductivity (κlat) via weak electron–phonon coupl...
