from 0.17 to 0.34 at 875 K for Co0.95Zn0.05SbS0.85Se0.15 sample, due to the noticeable decrease in the lattice thermal conductivity by introducing point defect, which is further confirmed by an analysis based on the Debye-CallawayKlemens model. Meanwhile, the thermoelectric power factor is maintained at high temperatures. This work highlights the important role of point defect in improving......
plane-wave pseudopotential method. The structural parameters of defect-free bulk rutile TiO2 were calculated, which are close to experimental data. And the effects of point defects on the geometry... defect comprised of Tii4+ and VTi4- would be formed in TiO2.
Key words: first-principles; TiO2; point defect; formation energy
