Title:
Feasibility Study of SrRuO3/SrTiO3/SrRuO3 Thin Film Capacitors in DRAM Applications 
Abstract:
In this paper, we have investigated the leakage current versus voltage characteristic of high-k thin film capacitors over a large temperature range. Fabricated samples, consisting of a 10-nm thin SrTiO3 (STO) layer as a dielectric material and SrRuO3 as electrodes, have been examined. Electrical measurements performed at different temperatures reveal leakage currents that exceed 10−7 A/cm2 at 1 V, a requirement needed for dynamic random access memory (DRAM) applications. We perfo...    »
