1. Used as "signal amplifier/rectifier" in radio and television.
Second, the development of "solar power generation" is also used for "solar cells".
3. Semiconductors can be used to measure temperature, and the temperature measuring range can reach 70% in production, life, medical care, scientific research, teaching and other fields. It has high accuracy and stability, and the resolution can reach 0.65438 0℃, even 0.065438 0℃. It is not impossible, the linearity is 0.2%, and the temperature measuring range is-100~+300℃. It is a temperature measuring element with high cost performance.
Fourth, the development of semiconductor refrigerators Semiconductor refrigerators are also called thermoelectric refrigerators or temperature difference refrigerators, which use the Peltier effect. /7c 1ed 2 1 b0ef 4 1bd 55d 14030256 da 8 1 CB 38 db 3d 85？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto
