Messung der spezifischen Wärme und der Fehlordnungsenergie von amorphen Blei-Wismut-Schichten

Measurements of specific heat and stored energy of amorphous lead-bismuth-films

Abstract

Amorphous Pb-Films with a 30 atomic-% Bi-content are produced by evaporation onto a cooled Be-foil at 20 °K in high vacuum. The specific heat of these films in the temperature range from 5–8 °K is found to be 1.6 times larger than after crystallization, which takes place during warming up between 30 and 40 °K. The stored energy released during this crystallization amounts to 1.5 kcal/mol.
