“…4,5 However, with the rapid development of electronic industry, electric devices including varistors are required to meet the ever-growing needs of miniaturization and integration, accompanying with higher performance and more functions, such as low breakdown electric field and high dielectric constant. 6 Because traditional SnO 2 varistors were sintered bulk ceramic materials and considering only the sintering processes is hard to reduce the size of ceramic devices by a wide margin, so a feasible method to decrease the geometry of a varistor markedly is necessary to meet the requirement of miniaturization. From this point, various film techniques are desirable.…”

A series of SnO x -Sb 2 O 3 thin film varistors were fabricated through hot-dipping tin oxide films deposited by radio-frequency magnetron sputtering in Sb 2 O 3 powder at varied temperatures in air. With the increase in hot-dipping temperature (HDT) from 200°C to 600°C, the nonlinear coefficient (a) of the samples increased first and then decreased, reaching the maximum at 500°C, which was mainly determined by the completeness of high-resistant Sb 2 O 3 layer at tin oxide grain boundary and the chemical composition of tin oxide films. Correspondingly, the leakage current (I L ) decreased first and increased later. The breakdown electric field (E 100 mA ) decreased constantly with increasing HDT. The SnO x -Sb 2 O 3 film varistors prepared at 500°C exhibited the optimum nonlinear properties with the maximum a of 10.88, the minimum I L of 36.3 mA/cm 2 , and an E 100mA of 0.0188 V/nm. The obtained nanoscaled film varistors would be promising in electrical/electronic devices working in low voltage.

With the development of material science and engineering, besides the most commercially available ZnO-based ceramic varistors, a wide variety of alternative ceramic systems have been remarkably expanded, including TiO 2 -, SrTiO 3 -, WO 3 -, CeO 2 -, and SnO 2 -based varistors.
