Abstract
The effects of acceptor dopant (typical Mn2+) and donor dopant (typical V5+) on the reliability of Li2ZnTi3O8 based low temperature co-fired ceramics (LTCC, in short) have been investigated. Large difference occurs among different types of dopants. V5+ doping decreases the breakdown voltage of the multilayer capacitors which were manufactured by low temperature sintered Li2ZnTi3O8 ceramics, however, Mn2+ doping increases the breakdown voltage and lowers down the leakage current significantly. This may very likely due to the fact that donor induces the generation of weak bound electrons while acceptor capture the weak bound electrons. The results suggest that Mn2+ is a very effective additive for improving the reliability of low temperature sintered Li2ZnTi3O8 ceramics.
