We have measured the I--V characteristics of tunnel junctions made of crossed nominally 50--60-A-thick aluminum films. Despite some gap broadening, the thermal I--V characteristics are those of weak-coupled superconductors. Under light irradiation, the films behave like homogeneous superconductors with the quasiparticles and phonons in equilibrium thermal distributions as a temperature above the bath temperature. The films behave as though the phonons are localized in the films despite the phonon wavelengths being considerably longer than the film thickness.
