Abstract

863,104. Temperature-sensitive resistors. SIEMENS-SCHUCKERTWERKE A.G. Feb. 27, 1957 [Feb. 27, 1956], No. 6532/57. Class 37. An electric circuit comprises a power thermistor consisting of a semi-conductor having a resistance-temperature characteristic which at first rises and then falls and having a large ratio between its electron and hole mobilities, the majority carriers having the lower mobility, and the semi-conductor operates on the rising part of its characteristic and also on the falling part. The semi-conductor may consist of P-type indium arsenide with zinc as impurity, or of any other A III B v compound or of Mg 3 Sb 2 . The fact that the thermistor is operating over the changeover region of positive to negative temperature coefficient increases the response to temperature change. Specification 748,799 is referred to.
