Messung der spezifischen Wärme von gestörten und amorphen Indium-, Blei-, Thallium- und Wismut-Schichten bei tiefer Temperatur

Thin metal films are evaporated onto a cooled Be-foil at 15–19 K in high vacuum. The specific heat is measured in the temperature range from 2.5–5 K after condensation and after annealing. The specific heat of disordered Pb- and In-films is about 1.5 times larger than that of annealed films. The additional contribution to the specific heat of amorphous Pb-, Bi- and Tl-films increases with decreasing temperature.
