It can be seen that the ZT of all composite samples is similar. As the temperature increases, the ZT gradually increases. After reaching the maximum value, the ZT gradually decreases as the temperature increases.
It can be seen that all composite specimenz TT is similar, with the temperature increases, ZT gradually increases, after reaching the maximum value, with the temperature increase, ZT gradually decreases.
It can be seen that the ZT of all composite samples are similar. With the increase of temperature, ZT increases gradually. When it reaches the maximum value, ZT decreases gradually with the increase of temperature.
