Abstract:

The method of L. Harris and B. Siegel, known under the name of instantaneous volatilization was used for producing uniform films, identical to the initial material in composition. This method consists of continuously feeding a fine-grained powder of the alloy in small portions to a crucible, which is at a temperature sufficient for volatilization of all components. The substrate temperature must be such as to avoid revolatilization of any condensing component of the alloy. An n-type alloy of the following composition was selected as the initial thermoelectric material 90 Bi2Te3 10 Bi2Se3 0.13 Hg2Cl2.
