摘要：

It is possible to prepare low-voltage varistors from TiO2 by doping with acceptors and by freezing in high-temperature defect equilibria. This leads to high-ohmic layers with potential barriers on a low-ohmic core of the samples. The feasibility to vary the electrical properties is very much restricted. © 1990.
