“…2 From the application point of view, the appreciated characteristics for TFRs are long-term stability, low temperature coefficient of resistance (TCR) in the dedicated operating temperature range, good ability for trimming, etc. [6][7][8] The most commonly used functional materials for TFRs are Ag-Pd, IrO 2 , RuO 2 , or ruthenates (typically Pb 2 Ru 2 O 6 , SrRuO 3 , and Bi 2 Ru 2 O 7 ), which possess excellent metallic conductivity and good chemical stability to air-firing. 7,9,10 Nevertheless, the precious metal elements (Pd, Ir, and Ru) contained in these materials are not conducive to lowering the cost in practical fabrication.…”

This work focuses on the evaluation of La 0.5 Sr 0.5 Co 1-x Zn x O 3 (LSCZ, x = 0.00-0.10) ceramics as an air-fireable and economical functional material for thick film resistors. Solid-state reaction experiments and first-principles calculations were conducted to investigate the crystal structure, thermal behaviors, and electrical properties of LSCZ ceramics. The substitution of Zn 2+ modified the bond properties, electron distribution, and band structure, resulting in more serious structural deformation, increasing the bond population of Co-O and weakening the charge transfer of LSCZ. Experimental results showed that the addition of Zn 2+ lowered the densification temperature, activation energy, and crystallite size. As the ratio of Zn 2+ increased, the conductivity and temperature coefficient of resistance showed a downward trend. Impedance variation with frequency and thermal aging tests were also performed. For the x = 0.05 specimen sintered at 1200 • C, values of 95.5% for relative density, 2857 S/cm for conductivity, 1267 ppm/ • C for temperature coefficient of resistance, -0.47% for conductivity change could be achieved.

“…The theoretical upper temperature limits for semiconductor materials – 150 °C for Si, 300 °C for GaAs, and 900 °C for 6H‐SiC are the main reason for operating‐temperature reduction of HTE devices . However, in practice these temperature limits are lower due to the operating temperatures of passive elements . Connections and packaging systems create many problems for HTE circuits .…”

The electrical properties of highly conductive ITO/Ag/ITO multilayer film at cryogenic temperatures have been presented in the paper for the first time. A good electrical conductivity and high thermal resistance of ITO/Ag/ITO are desirable features at cryogenic temperatures. Elements in ITO/Ag/ITO (AgHT™) were patterned using fiber laser ablation. Close to a linear (R2 = 0.999) relationship between resistance and temperature in the range of 293–55 K was confirmed. The dynamics of resistance changes is of the order of 9 × 10−4 1/K. Carrier concentration and mobility have been determined on the basis of Hall voltage measurements. Structures patterned in AgHT™ conductive film can be seen to be suitable for passive elements of low‐temperature electronics.
