摘要：

The thermoelectric properties of Mo3Te4 are evaluated in the temperature range from room temperature to about 1000 K. The elastic constants and Debye temperature of Mo3Te4 are also evaluated from sound velocity measurements made by the ultrasonic pulse-echo method. The relationships between several properties of Mo3Te4 are studied. The electrical resistivity of Mo3Te4 is slightly lower than that of state-of-the-art thermoelectric materials. The absolute values of the Seebeck coefficient are relatively low, increase with increasing temperature, and reach a maximum value of about 25 muV K-1 at 1000 K. The thermal conductivity of Mo3Te4 increases gradually with increasing temperature, showing metallic behavior. The maximum value of the dimensionless figure of merit is 0.015 at about 1000 K.
