What property of semiconductors is used in thermistors? in photoresistors?
| September 24, 2020 | Education
As the temperature rises, the number of free electrons and, accordingly, holes in the semiconductor increases significantly. This leads to the fact that the resistivity of the semiconductor decreases when heated. With increasing illumination, the number of free electrons and, accordingly, holes in the semiconductor also increases significantly, which leads to a decrease in its resistivity.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
