Tested experimental exploitation order
Description of the development:
()
Synthesis technology (doping) using the "rocking furnace" is to increase the synthesis of deduction by mechanical mixing of the components during the synthesis of the material. Owing to the mixing of the material, increasing its uniformity (uniform distribution of the dopant). Thermocouple threads made of the synthesized material are more thermoelectric parameters compared with branches made of samples synthesized by RPK (vapor-liquid-solid).
On the basis of synthesized materials can be made experimental samples of various microelectronic devices (thermoelectric transducers, detectors, sensors, etc.).
