Nature of potential barrier in (Ca-1/4,Cu-3/4)TiO3 polycrystalline perovskite
(Elsevier B.V., 2006-01-01)
The nonohmic electrical features of (Ca-1/4,Cu-3/4)TiO3 perovskite ceramics, which have very strong gigantic dielectric is believed originate from potential barriers at the grain boundaries. In the present study, we used ...

Dielectric and non-ohmic analysis of Sr2+ influences on CaCu3Ti4O12-based ceramic composites
(2021-02-01)
In this study, CaCu3Ti4O12 ceramic composites were prepared through solid-state reaction by adding Sr2+ and removing Cu2+. Application of the Rietveld method and structure refinement revealed the presence of pure CaCu3Ti4O12 ...
Non-Ohmic and dielectric properties of a Ca2Cu2Ti4O12 polycrystalline system
(American Institute of Physics (AIP), 2006-11-20)
An investigation was made into the non-Ohmic and dielectric properties of a Ca2Cu2Ti4O12 perovskite-type system. Compared to the traditional CaCu3Ti4O12-based composition, the imbalance between the Ca and Cu atoms caused ...

SnO2, ZnO and related polycrystalline compound semiconductors: An overview and review on the voltage-dependent resistance (non-ohmic) feature
(Elsevier B.V., 2008-01-01)
The present review describes mainly the history of SnO2-based voltage-dependent resistors, discusses the main characteristics of these polycrystalline semiconductor systems and includes a direct comparison with traditional ...

Comparative degradation of ZnO- and SnO(2)-based polycrystalline non-ohmic devices by current pulse stress
(IOP PUBLISHING LTD, 2008)
The degradation behaviour of SnO(2)-based varistors (SCNCr) due to current pulses (8/20 mu s) is reported here for the first time in comparison with the ZnO-based commercial varistors (ZnO). Puncturing and/or cracking ...
