The effect of the resistance R of Mn1.s5 Coo.3Nio.85 O4 (MCN) thick-film negative-temperature-coefficient (NTC)thermistors on temperature T is studied carefully.Interestingly,the R-T relation is found to be decided simultaneously by the characteristic of the MCN oxide and the electrode structure of the NTC thermistor.For plane end electrodes,the R T relation is nonlinear.However,for plane fork electrodes,the R-T relation can belinear.To clarify the intrinsic mechanism of the linear R-T relation,the electric field distribution in the MCN thick film is simulated.The obtained results suggest that the non-uniform electric field distribution between the electrodes is responsiblefor the R-T relation linearization.
