Surface excitations in thin helium films

Creators

  • 1. Univ. of Illinois, Urbana

Description

The temperature dependence of third-sound velocity below 0.70K has been measured in thin helium films. We have observed phonon-like two-dimensional thermal excitations whose density is independent of film thickness for films thinner than 2.8 atomic layers
