Dielectric constants of Ir, Ru, Pt, and IrO2: Contributions from bound charges

W. S. Choi, S. S. A. Seo, K. W. Kim +3

We investigated the dielectric functions $\epsilon$($\omega$) of Ir, Ru, Pt, and IrO${}_2$, which are commonly used as electrodes in ferroelectric thin film applications. In particular, we inves…
