About this item

  • ✦Prices in the size catalog are per 100g
  • ✦The important characteristic of N-type semiconductors is that after a certain amount of a certain impurity penetrates into the semiconductor, it can not only greatly increase the electrical conductivity, but also manufacture semiconductors of different properties and different uses according to the type and amount of impurities incorporated. When an impurity is incorporated into a semiconductor, free electrons are released, which is called an N-type semiconductor
  • ✦P-type semiconductors use "holes" to conduct electricity. Under the action of external electric field, the "hole" flow direction and the electron flow direction are opposite, that is, the "hole" flows from the positive plate to the negative electrode, which is the P-type semiconductor source
  • ✦Advantages of temperature difference power generation: no noise, simple installation, long life, stable performance
  • ✦Temperature difference cooling components have been widely used in experimental instruments, consumer products and industry
  • ✦100g/Package


✦Semiconductor thermocouples are composed of N-type semiconductors and P-type semiconductors. N-type materials have excess electrons and a negative thermoelectric potential. P-type materials lack electrons and have positive thermoelectric potential; When electrons pass through the node from P-type to N-type, the temperature of the node decreases, and its energy must increase, and the increased energy is equivalent to the energy consumed by the node. Conversely, as electrons flow from the N-type to the P-type material, the temperature of the junction increases.
