description: This work contains information on fundamental thermoelectric effects, design,
and operation principle of thermoelectric modules. Current data on physical
and chemical properties of Bi2Te3 and thermoelectric efficiency of material are
given. Promising methods of obtaining single-crystal semiconductor samples are
considered.
The study set a challenge. On the Bi2Te3 crystals grown by the Chohralski
method, obtain the necessary data on the zone structure of the material. For this it
was necessary to measure several experimental dependencies, in particular: the dependence
of thermoedes, the Nernst effect - Ettingshausen, the Hall coefficient, electric
conductivity on temperature. The temperature range in this case was 77-450 K.
As a result, zone parameters are estimated, values of effective mass of holes
and energy gap between non-equivalent extremes are given. The resulting dependencies
and the fact that there are free inter-zone transitions indicate a complex zonal
structure of the Bi2Te3.
