Abstract in another language

The study compares thick-film NTC thermistor devices, produced by the screen-printing (and firing) technique and by the Aerosol Deposition Method (ADM) at room temperature. The devices are compared with respect to film quality (optical, mechanical) and to the negative temperature coefficient of resistance (NTCR) parameters ρ25 and B. While the screen-printed films are porous, the Aerosol Deposited (AD) films are characterized by high tightness, mechanical stability, and a production at room temperature. The electrical analysis shows that the AD films reach the ρ25- and B values of bulk NTCRs from literature after a moderate tempering step below 400°C in air.The screen-printed films show B-values that are comparable to the values of bulk NTCRs from literature and ρ25-values that are significantly higher.
