在低温中,半导体 pn 结的电容和温度之间有很密切的关系。利用这种特性,可以制成新型的电容温度计。这种电容温度计的特点之一是使用简便,而且能作高精度的温度测量和控制。由于它的灵敏度和相对灵敏度都比较高,如果能够研制出不受磁场影响的温度计结构,那么,这种新型的温度计就可能成为大有希望的极低温用的电容温度计。为了使磁场的影响
At low temperatures, there is a close relationship between the capacitance and temperature of the semiconductor pn junction. Using this feature, you can create a new type of capacitance thermometer. One of the features of this capacitance thermometer is its ease of use and its ability to perform high-precision temperature measurement and control. Due to its high sensitivity and relative sensitivity, the new thermometer could be a promising cryogenic capacitance thermometer if a thermometer structure was developed that is unaffected by the magnetic field. In order to make the magnetic field influence
