%X The leakage current mechanism of (Ba,Sr)TiO3 capacitors were examined for dynamic random access memory applications. Leakage currents were measured in the temperature range 20-150 °C, and the data was analyzed for the various mechanisms. The extracted dielectric constant, corresponding to Poole-Frenkel mechanism, is in good agreement with the experimental value of the optical dielectric constant.
