1. A structure of a thermoelectric film comprising:
a thermoelectric substrate; a pair of first diamond-like carbon layers respectively sandwiching two opposite surfaces of the thermoelectric substrate and having a resistivity ranging from about 10−4Ω-cm to about 10−1Ω-cm; a pair of metal interface layers, respectively stacked on the first diamond-like carbon layers and on sides of the first diamond-like carbon layers away from the thermoelectric substrate and having a resistivity ranging from about 10−3Ω-cm to about 10−4Ω-cm; a pair of metal layers, respectively stacked on the metal interface layers and on sides of the metal interface layers away from the first diamond-like carbon layers and having a resistivity ranging from about 10−5Ω-cm to about 10−6Ω-cm; and wherein the thermoelectric substrate, the first diamond-like carbon layers, the metal interface layers, and the metal layers are electrically conductive; and stacked in a direction perpendicular to the two opposite surfaces of the thermoelectric substrate.
