THERMOELECTRIC SENSOR USING GE MATERIAL

摘要

PURPOSE: A thermoelectric sensor using a GE-based thermoelectric material is provided to lower heat conductivity, resistance, and high-sensitivity noise. CONSTITUTION: A thermoelectric sensor using a GE-based thermoelectric material comprises substrates(10) and film type thermopiles. The film type thermopiles are formed on the top surface of the substrates. The thermopile is composed of a semiconductor thermocouple which has germanium. When the thermocouple is formed, a p-type semiconductor and an n-type semiconductor are welded. The p-type semiconductor is formed by doping Ga in the germanium. The n-type semiconductor is formed by doping As in the germanium.
