摘要：
The combined leakage current model of thermionic emission and carrier drift diffusion mechanisms is derived from previous studies for (Ba, Sr)TiO3 (BST) thin films. Numerical simulations have been performed to investigate the effects of space charge on the leakage currents of BST thin films with Pt electrodes. The effects of the magnitude of the net donor concentration and the heavily charged depletion layers at both cathode and anode interfaces have been studied. (c) 2005 Elsevier B.V.
