Abstract
A temperature detector having a semiconductor layer which is a p-type or n-type semiconductor doped by addition of an impurity. The semi- semiconductor is completely amorphous, or substantially amorphous with the inclusion of microcrystals. The temperature detector has good sensitivity at a temperature of not more than 100 K, and has good linearity of the change of resistivity to the change of temperature over a wide range of temperature.
