Thermoelectric phenomena can be strongly modified in nanostructures. The determination of the Seebeck coefficient (S) in nanomaterials is a challenge since the mechanisms are different from the bulk. Here, we demonstrate a strong variation in S induced by electron-phonon interactions. Microscopic mechanisms are identified by using thermoelectric voltage dependencies as fingerprints. We found that different mechanisms can dominate, depending on the hybrid system. Our improved understanding will contribute to the future control of thermoelectric effects on nanoelectronic devices.
