Abstract
The effect of extremely high temperatures developing on surface
during the condensation of sputtered atoms has been discovered for
the first time by direct surface temperature measurements. This
temperature is considerably higher than the temperature of solid
film beneath and proportional to the flux of atoms impinging on the
surface. Surface temperature steeply grows as the condensation
starts, exists during the period of condensation and rapidly decays
after its stopping. The effect is related to the anomalously low
thermal conductivity of superficial layer that is formed by highly
mobile atoms arriving on the condensation surface. This superficial
layer can be viewed as a new state of matter characterized by its
anomalously low thermal conductivity.
