Abstract
We describe a simple electron-heating experiment in which the phonon escape from thin metal films is changed in situ. This provides clear evidence that the phonon-escape rate can significantly affect electron heating. From the results we have determined that phonon generation by the heated electrons and phonon escape have comparable rates.Keywords
