Conductor elements can be connected in a variety of ways to meet the user's requirements
Semiconductor elements can be connected in a variety of different ways to meet the user's requirements. Coupling a P-type semiconductor element and an N-type semiconductor element to form a thermocouple pair, connected to a DC power supply, creates a temperature difference and heat transfer at the joint.

Semiconductor thermocouples consist of N-type semiconductors and P-type semiconductors
Semiconductor thermocouple consists of N-type semiconductor and P-type semiconductor. N-type material has excess electrons and has negative temperature difference potential. P-type material has insufficient electrons and has positive temperature difference potential; when current flows from N-type through the junction to P-type, the temperature of the junction decreases and its energy must increase, and the increased energy is equal to the energy consumed by the junction. On the contrary, when the current flows from P-type to N-type material, the temperature of the junction increases.
