We have investigated the thermoelectric properties of MoO3 monolayer and its defective structures with oxygen vacancies by using first-principles method combined with Boltzmann transport theory. Our results show that the thermoelectric properties of MoO3 monolayer exhibit an anisotropic behavior which is caused by the similar anisotropic phenomenon of electronic conductivity and thermal conductivity. Moreover, the creation of oxygen vacancies proves to be an effective way to enhance the ZT values of MoO3 monolayer which is caused by the sharp peak near the Fermi level in density of states. The increased ZT value can reach 0.84 along x-axis at 300K.

Thermoelectric Application

Electrical conductivity and thermopower of Bi2Sr3Co2Ox sintered bodies were first investigated in the temperature range 440–1060 K in air for high-temperature thermoelectric application. The samples fabricated by the sinter-forging method increased their bulk densities and electrical conductivity. The value of thermopower and the temperature dependence of electrical conductivity of the sinter-forged samples were close to that of the single crystal. Evaluating the thermal conductivity of the polycrystalline sample, we calculated a thermoelectric figure of merit Z to be 0.107 × 10−3 K−1 at 1060 K.
