We compare the confinement-induced nonlocal electromagnetic response model to the standard local Drude model routinely used in plasmonics. Both of them are applied to study the heat transfer for transdimensional plasmonic film systems. The former provides greater Woltersdorff length in the far-field and larger film thicknesses at which heat transfer is dominated by surface plasmons, leading to enhanced near-field heat currents. Our results show that the nonlocal response model is capable of making a significant impact on the understanding of the radiative heat transfer in ultrathin films.
