- Electron and lattice heat transport have been investigated in bilayer thin films of gold and CoSb$_3$ after photo-excitation of the nanometric top gold layer through picosecond x-ray scattering in a pump-probe setup. The unconventional observation of a larger portion of the deposited heat being detected first in the underlying CoSb$_3$ layer supports the picture of ballistic transport of the photo-excited electrons from gold to the underlying layer. The lattice expansion recorded by x-ray scattering allows accounting for the energy deposition and heat transport.
