## Description

- description: In the present study, for the first time, aluminum-doped zinc oxide
    (AZO) thin films with nanoinclusions of amorphous carbon have been synthesized
    via spin coating, and the thermoelectric performances were investigated varying
    the aging period of the solution, the procedure of carbon nanoparticles’ addition,
    and the annealing atmosphere. The addition of nanoparticles has been pursued to
    introduce phonon scattering centers to reduce thermal conductivity. All the samples
    showed a strong orientation along the [002] crystallographic direction, even though
    the substrate is amorphous silica, with an intensity of the diffraction peaks
    reaching its maximum in samples annealed in the presence of hydrogen, and generally
    decreasing by the addition of carbon nanoparticles. Absolute values of the Seebeck
    coefficient improve when nanoparticles are added. At the same time, electric conductivity
    is higher for the sample with 1 wt.% of carbon and annealed in Ar with 1% of H2,
    both increasing in absolute value with the temperature rise. Among all the samples,
    the lowest thermal conductivity value of 1.25 W/(m·K) was found at room temperature,
    and the highest power factor was 111 μW/(m·K2) at 325 ◦C. Thus, the introduction
    of carbon effectively reduced thermal conductivity, while also increasing the
    power factor, giving promising results for the further development of AZO-based
    materials for thermoelectric applications.
