Description
Summary:This paper reviews the properties of a range of Ge-on-GaAs film resistance thermometers that cover the temperature range 0.03 K to 500 K. A new dual element resistance thermometer is described, in which two temperature sensitive elements with overlapping thermometrical characteristics are combined to provide a thermometer with good sensitivity over the measurement range from 0.1 K to 400 K. A novel dual function sensor for concurrent measurements of temperature from 1.5 K to 400 K and magnetic field is also described. This consists of a Ge-GaAs resistance thermometer and an InSb-GaAs Hall-effect magnetic field sensor combined in a single package.
