| Abstract: | The surface dynamics of supercooled liquid-glycerol is studied by
scanning the thickness of the glycerol film with single photon
detection. Measurements are performed at room temperature well above
the glycerol's glass transition temperature. It is shown that the
surface dynamics of the glycerol film is very sensitive to the
temperature. The linear relationship between the thickness of the
film and the viscosity predicted by the Vogel--Fulcher--Tammann--Hesse
(VFTH) law is also presented experimentally. |
