RESISTANCE AND STRAIN RESISTANCE PROPERTIES OF SOLID SOLUTIONS TlIn1-xCoxSe2 (0 ≤ х ≤ 0.5)

The paper presents the results of a study of the effect of the ratio of cobalt components on the electro-physical and strain-resistive characteristics Of tlin1-xcohse2 alloys in the concentration range of cobalt x = 0-0.5. it is established that in the range of x = 0 - 0.02 these properties have linear concentration dependencies, which undergo sharp changes in the range of 0.02 - 0.5. It was found that with an increase in temperature in the region of 300 ≤ Т ≤ 410 K, the sensitivity to deformation in all investigated compositions of the solid solution TlIn1-xCоxSe2 significantly increases. Keywords: ratios of cobalt components, electro-physical, strain-resistive characteristics, concentration range
