Crystal thermoelectric
WebThe first thermoelectric (TE) properties of simple polyol method-synthesized Cu1–xBixS (x = 0, 0.02, 0.04, 0.06) nanosheets are reported here. Various characterizations like … Strategies to improve thermoelectric performances include both advanced bulk materials and the use of low-dimensional systems. Such approaches to reduce lattice thermal conductivity fall under three general material types: (1) Alloys: create point defects, vacancies, or rattling structures (heavy-ion species with large vibrational amplitudes contained within partially filled structural sites) to scatter phonons within the unit cell crystal; (2) Complex crystals: separate the phonon glass fro…
