Abstract

In order to elucidate the origin of the characteristic dielectric response of CaCu3Ti4O12 (CCTO), we synthesize c-axis oriented multilayer thin films composed of alternative layers of CCTO and an insulator CaTiO3 (CTO) using the Pulsed Laser Deposition (PLD) method and measure the capacitance of CTO/CCTO/CTO multilayer thin films with different thicknesses of CTO and CCTO layers. After removing the extrinsic electrode/CCTO boundary effect and the CCTO/CTO interface effect, the inherent dielectric constant of CCTO is determined.
