MANGANESE OXIDE THERMISTORS. SPECIAL TRANSLATION

Abstract

Experimental investigation of the electrical and thermal properties of thermistors made on manganese oxides confirms the correctness of the hypothesis which states that the investigated specimens are actually solid electrolytes. Theoretical formulas are derived for the temperature dependence of the coefficient of heat conductivity and thermal emf. Empirical laws are determined to characterize the dependence of the resistance of specimens on temperature, and the dependence of the charge-carrier mobility in the specimens on activation energy. In thermistors made of manganese oxides, O ions, which are the charge carriers, also take an active part in the process of heat transport. In the presence of a temperature gradient in a thermistor semiconducting substance, a nonuniform concentration of O ions appears which leads to the appearance of an emf in the thermistor. (Author)
