Abstract:
We investigated dielectric properties of La 1- x Eu x Nb 2 O 7 perovskite nanosheets in order to study the effect of A -site modification on dielectric properties. Langmuir–Blodgett deposition was employed to fabricate multilayer nanofilms of perovskite nanosheets. In these nanosheets, A -site modification with Eu 3+ ions improves the leakage current characteristics and, at the same time, reduces permittivity. The slight modification with Eu 3+ ions in La 0.95 Nb 2 O 7 nanosheets causes a 50% reduction in ε r value. We also discuss the high-κ properties of La 0.95 Nb 2 O 7 nanosheets by performing detailed investigations based on first-principles calculations and interfacial structures.
