The presented article provides a comparative analysis of the methods of manufacturing technology for semiconductor branches of p- and n-type conductivity. For comparative analysis, a method is considered for obtaining ternary alloys based on the Bi2Te3 base material by pressing and zone melting. The sequence of the manufacturing process, the principles of operation and design of devices used to obtain alloyed substances, as well as methods for studying and measuring the electrophysical parameters of the thermoelement legs included in the assembled thermopile are described. The principles of automatic temperature control of an electric furnace by a two-position method are indicated. The advantages of the zone melting method are determined and the best values of the figure of merit of a thermoelectric material are shown. It is proved that the original values of the parameters of the branches are preserved after they are assembled into a battery.
Key words: The design / horizontal zone melting plant / melting technology / temperature control / thermoelectric / Seebeck effect / Hall effect / thermal conductivity
