## Description

- description: Thermoelectric materials can utilize the Seebeck effect to convert
    electrical into thermal energy and vice versa. State-of-the-art research focuses
    on semiconductors as the band gap in their electronic density of states results
    in large values of the Seebeck coefficient. However, recent results suggest that
    certain metallic alloys such as NixAu1−x can also feature promising thermoelectric
    properties, relevant for technological applications [Sci. Adv. 9, eadj1611 (2023)].
    In this work, we study the thermoelectric properties of NixAu1−x films on different
    substrates, with additional focus on a cost-efficient synthesis. Ultimately, a
    large power factor of 11.2mW/mK2 is achieved at 614K in Ni0.27Au0.73. Furthermore,
    by neglecting the phonon contribution to thermal conduction, which is negligibly
    small in these metallic systems well-obeying the Wiedemann-Franz law, a figure
    of merit of zT = 0.15 is obtained at 763 K.
