Abstract
A method of preparing a thermoelectric material includes the following steps. A thermoelectric raw material can be filled into a cavity of a first mold so that the thermoelectric raw material filled in the cavity has first and second dimensions. The first dimension can be defined in a first direction. The second dimension can be defined in a second direction. The second direction can be perpendicular to the first direction. The first dimension can be equal to or greater than the second dimension. The thermoelectric raw material filled in the cavity can be cooled in a uniaxial direction that is parallel to the second direction at a cooling rate of at least 600° C./min.
