Abstract
By heating the droplet cloud in Ge with infrared radiation, we increase the low-frequency phonon emission rate of the droplets. By measuring the resulting velocity increase, we give convincing evidence that this "phonon wind," powered by Auger decay, is the cause of droplet motion, as originally proposed by Keldysh.Keywords
