High-entropy neg. temperature coefficient (NTC) thermistor thin films, renowned for their exceptional stability, represent a significant advancement in the field of temperature measurement, facilitating the miniaturization of next-generation information and electronic devices.However, "trial and error" approach to developing multi-component NTC oxides significantly constrains the efficiency of the design process.To accelerate development process, we prepared Co-Mn-Fe-Ni-Zn-O gradient films by co-sputtering combinatorial synthesis.The effects of stoichiometric ratios on the resistance (R25), material constant (B25/50) and stability (ΔR/R0) of gradient films were visually represented through color-coded maps for straightforward and intuitive anal.Samples close to the MnCoFe target in gradient films showed a trend of decreasing resistance and increasing material constant, both reaching 1.71 MΩ and 4083 K, resp.The high-entropy Co21Mn17Fe19Ni21Zn22O4±v film exhibited the lowest resistance drift rate only 2.68 % after 500 h ageing at 125 °C.Another delightful result was that the corresponding homogeneous films, achieved through sputtering with a composite target, had a relative deviation in resistance drift rate of merely 0.18 %.This showcased the successful translation from the screening outcome to the homogeneous film, significantly accelerating the development of NTC materials via the utilization of gradient films screening.
